Although the ancient Jews were not
especially noted for their overall knowledge of the theoretical
sciences, they were well versed in the technology skill of purifying
metal ores to obtain valuable metals such as gold and silver.
Therefore it is not unusual that metallurgical terminology was often
employed in the Bible, both Old and New Testaments, as a metaphor.
In my own experiences in the field of
organic chemistry, I gained a minor reputation during my
undergraduate research by being able to separate the desired chemical
products from any associated impurities through techniques such as
selective recrystallization and column chromatography. However, in
the field of inorganic chemistry such as is the case here, completely
different methodologies are employed, as described by Keener:
“Heating a furnace sufficiently
allowed ancients to extract precious metals from ore: lead melts
already at 327 degrees C, and its main ore would be heated to 900 or
1000 degrees C to extract silver. Gold remains long after lead,
melting only at 1063 degrees C. Thus gold would remain after most
other ore was removed.”
However, Keener only describes a
physical process for separating metals from their ores. But it was
almost always accompanied by addition of a flux which chemically
reacted with the base metals present so that the resulting dross
could be scooped off the top of the molten metal to further purify
it. This was especially helpful in purifying gold since it is
chemically inert to almost all reagents.
And as to the underlying meaning of
this biblical metaphor, Keener adds:
“Believers who stand firm in the
testing prove faithful; the language of 'testing' can include the
nuance of those who pass the test being 'approved.' Just as testing
refines gold and improves the final product as pure gold, so testing
improves those who persevere through it.”
Deuteronomy 4:20 “The
temperatures reached in the iron smelting furnaces were the highest
known in biblical times and are used to indicate the unpleasantness
of life in Egypt (Deut 4:20; I Kings 8:51; Jer 11:4).” (Dictionary
of Biblical Imagery)
I Kings 8:51 “...for they are
your people and heritage which you brought out of Egypt, from the
midst of the iron-smelter.”
Cogan: “Egypt, mostly known as a
'slave-house,' was compared in Deuteronomic circles to a blast
furnace used for smelting iron ore, so harsh were the conditions of
life.”
Job 23:10
The second half of this verse reads,
“When he tests me, I shall emerge as gold.”
“Job's use of the analogy of
purifying gold for his own testing is another indication that the
basic motivation for his lament is the restoration of his own honor,
not the restoration of his wealth. With this metaphor Job is
rebutting Eliphaz's exhortation to lay aside gold (22:24-25) and to
make God his gold. Rather than owning the precious metal, Job longs
for a golden character.” (Hartley)
Psalm 12:6 This verse
states that God's promises are pure just as silver is refined in a
furnace.
Anderson explains that “God's
promises or words are compared with purified silver, which is in a
sense true silver, i.e. its quality can be relied upon. This
word-picture would have been well known, because the purity of silver
had great importance in business transactions, for silver was one of
the main media of exchange.”
Psalm 66 “For you, O
God, have tested us; you have tried us as silver is tried.”
Tanner says that “the testing of v.
10 is clearly reminiscent of how the Israelites tested God at Massah
(Exod. 17:7; Deut. 6:16; 33:8; Ps. 95:8-9).” Only here the tables
are turned.
Proverbs 27:21 The
Anchor Bible translation reads: “The crucible is for silver and the
furnace for gold, and a person is tested according to his praise.”
Ruiz calls this “an idiom for
removing sin from one's life.” And Waltke explains that it can mean
either (a) “one is tested by the character of the one who praises
him” or (b) “a person's mettle is tested by whom or what he
praises.”
Isaiah 1:25 “I will smelt
away your dross as with lye and remove all your alloy.” Other
translations read something like: “I will burn away your dross
completely. I will take away all your impurities.” In either case,
as Oswalt puts it, “God's hand will not be upon them to destroy but
rather to restore. The slag and the tin will be removed; the rulers
will be as they once were, and the city name, City of Righteousness,
whether an ideal past or an actual one is in view here...the prophet
looks forward to a time when God's people, having passed through the
fires, will relate to him, and thus to one another, as they ought.”
Isaiah 48:10 “See, I have
refined you, but not like silver; I have tested you in the furnace of
adversity.”
The reference is to the experience of
exile in Babylon whereas in Deuteronomy 4:20 and Jeremiah 11:4 it
refers to the Jews' time in Egypt. (Blenkinsopp)
Jeremiah 6:27-30 Here we have
an extended metaphor in which “lead is added to silver ore in the
furnace to act as a flux to remove impurities. The image speaks of
God's attempt to purify Israel by removing the impurities of the
wicked under the Babylonian onslaught.” (DBI)
Jeremiah 11:4 speaks of the time
when God delivered the Jews from the “iron furnace” of Egypt.
Cawley and Millard say, “It marked
their deliverance from the iron furnace, the smelting oven
being symbolic of intense suffering.”
Ezekiel 22:17-22 states that
Israel has become dross. As Cook puts it, “The judgment will be
like a smelter in which base metals are removed.”
Daniel 11:35 “Some of the
wise shall fall, so that they may be refined, purified, and cleansed
[lit. 'made white'] until the time of the end...”
“In 11:35, the author speaks again of
the wise leaders of the Jews first mentioned in 11:33 and later in
12:3,10; here the purpose of their being 'tested' is stated
explicitly...The Deuteronomic theology of retribution...did allow the
possibility of adversity serving as a test of fidelity or as a means
of purification, as here...Our author may have had some feeling for
the Maccabean revolt, but his true sympathies lay with those engaged
in non-violent resistance. It was their suffering love unto death
that would 'refine, cleanse, and purify' the nation and vindicate the
principles of true religion which no human power can crush.”
(Hartman and DiLella)
But not everyone agrees entirely with
the above view. For example, Longman says, “I believe it is
wrong-minded to say that the book of Daniel represents a pacifist
view that waits for God the warrior to act. In the earlier historical
battles of Israel, God won the war, to be sure, at places like
Jericho, but that did not mean that Israel did not take action in
some way. In other words, the ideology of the book has plenty of room
for appreciation of armed resistance to the oppression.”
Daniel 12:10 “Many shall be
purified, cleansed, and refined, but the wicked shall continue to act
wickedly.”
This verse is part of an obscure
prophecy regarding the consummation of the last days. Kaiser
concludes “that Daniel knew all but two aspects of the prophecies
revealed to him: (1) the temporal aspects (an exclusion we share even
today, as noted I Pet 1:10-12) and (2) additional information beyond
that revealed to him. No prophet claimed omniscience, only an
adequate, God-given knowledge of a limited topic of importance.”
Zechariah 13:8-9 The prophecy
in this verse says that 2/3 of Israel will be cut off and the
remaining 1/3 refined as silver or gold.
“Zechariah 13:7-9 is...a fitting
conclusion to the series of shepherd-flock units, since it moves
beyond the judgment envisioned in the earlier units and reveals the
purification that results from such severe discipline...The image
world for the first half of v. 9 is clearly that of metallurgy, a
common image in prophetic literature. The third of the community
which survives Yahweh's initial discipline is described as a precious
metal like silver and gold. It is not certain whether
the impurities which are removed through this process refer to
dysfunctional qualities and patterns within the community, or to
offending parties within the community.” (Boda)
I Peter 1:7
“The term rendered as genuineness
was often used for unalloyed metals; fire tested their genuineness,
as it tests that of believers. For believers, the figuratively fiery
testing refers to sufferings in the present age; as in 4:12, it
probably envisions for Peter's audience especially persecution. The
imperishable inheritance of 1:4 is worth far more than perishable
gold (1:7)... Gold may endure testing by fire, but faith that is
tested by fire proves far more permanent and will be honored once
Christ returns. This is because believers were bought not with
perishable silver or gold (1:18), valuable merely outwardly (3:3),
but with the far more precious blood of Christ (1:19).” (Keener)
Revelation 3:18 The letter to
the church of Laodicea says, “I counsel you to buy from me gold
refined by fire so that you may be rich.”
Mounce explains: “The gold is
spiritual wealth that has passed through the refiner's fire and has
been found to be totally trustworthy.”
And Morris says, “For this threefold
deficiency [given in verses 15-17] the remedy in each case is Christ.
From Him they should buy gold tried in the fire (cf. I Pet. I. 7),
real wealth.”
