(18) Become dross.--The second prophecy (Ezekiel 22:17-22) is occupied with a figure taken from the refining of silver, which is a favourite one with the prophets (see Isaiah 1:25; Jeremiah 6:29; Zechariah 13:9; Malachi 3:3). The peculiar appropriateness of this figure has been often noted in the fact that the completion of the process of refining silver in the furnace was determined by the parting of the floating dross and the reflection of the image of the refiner from its molten surface. This figure, while setting forth the punishment of Israel, shows clearly that this punishment was for the purpose of purification.

Verse 18. - The house of Israel is to me become dross, etc. A new parable, based upon Isaiah 1:22, 23 and Jeremiah 6:80, begins, and is carried out with considerable fullness. In Malachi 3:2, 3 we have the same imagery. Baser metals have been mingled with the silver, and must be burnt out, but there is hope, as well as terror, in the parable. Men throw the mixed metals into the smelting-pot in order that the silver may be separated from the dross and come out pure (comp. 1 Peter 1:7). And this was to be the issue of the "fiery trial" through which Jerusalem and its inhabitants were to pass.

22:17-22 Israel, compared with other nations, had been as the gold and silver compared with baser metals. But they were now as the refuse that is consumed in the furnace, or thrown away when the silver is refined. Sinners, especially backsliding professors, are, in God's account, useless and fit for nothing. When God brings his own people into the furnace, he sits by them as the refiner by his gold, to see that they are not continued there any longer than is fitting and needful. The dross shall be wholly separated, and the good metal purified. Let those who suffer pains, or lingering sickness, and find that their hearts can scarcely bear these light and momentary afflictions, take warning to flee from the wrath to come; for if these trials are not sanctified by the power of the Holy Spirit, to the cleansing their hearts and hands from sin, far worse things will come upon them.Son of man, the house of Israel is to me become dross,.... Vile, despicable, useless, and unprofitable; to which the wicked of the earth are compared, Psalm 119:119 and here the Lord's professing people, they differing nothing from them, being sadly degenerated; formerly they were as silver, and so they might be reckoned among themselves; but to God, who is omniscient, the searcher of the hearts and reins, who saw all their actions, and knew the spring of them, in his sight they were as dross:

all they are brass, and tin, and iron, and lead, in the midst of the furnace: or "crucible" (f); where they are put together, in order to be set in the furnace, and melted down. It is not usual to put so many different metals together for melting, but separately; but here it seems to intend a mixture of them all together; and so the Targum and Septuagint render it,

"all they as brass, &c. are mixed;''

several metals of the baser sort are here mentioned, by a gradation from the better to the worse; tin being not so good as brass, and iron of less value than either, and lead than any of them. Some think the different characters of the people are here described; impudent persons by "brass"; hypocrites by "tin"; cruel and savage ones by "iron"; and such as were sottish and stupid by "lead"; or, as others, covetous ones:

they are even the dross of silver; once they were like silver, precious and valuable, while they retained the true religion, and the worship of God, and behaved agreeably to their character in the performance of all good works, and were in outward flourishing circumstances; but now degenerated from the pure worship of God, and sunk into idolatry and wickedness, and become poor and miserable.
