Isa 1:25

“For we will not mimic the false prophets who say that most things have been done by them. This is the meaning of "to corrupt," when someone dilutes the wine, or when someone sells something which ought to be given away freely. He seems to me to be both taunting them regarding money and hinting at the fact that they have mingled the things of God with their own things, as I have said. This is the accusation of Isaiah, who says, "Your wine merchants mingle wine with water." Even if this statement were about wine, one would not sin to say it of doctrine as well. He says, "We do not do this, but we offer to you what we have been given, pouring out the undiluted word."”

“This occurs for the sake of cleansing, however, when he humbles his righteous ones for their small and as it were insignificant sins or because of their proud purity, giving them over to various trials in order to purge away now all the unclean thoughts … which he sees have collected in their inmost being, and in order to submit them like pure gold to the judgment to come, permitting nothing to remain in them that the searching fire of judgment might afterwards find to purge with penal torment.”

“And I will return My hand upon you One blow after another, until the transgressors have been completely destroyed. as with lye This is an expression meaning soap [sbon in O.F., savon (in modern French)]. Its deviation is an expression of cleanliness, similar to (Ps. 24:4): “and pure (בַּר) of heart,” since it cleanses the garment of its stains. your dross mentioned above, as: “Your silver has become dross”; a mixture of silver with copper is called dross. Here too, a mixture of the wicked with the righteous. I will destroy the transgressors, who are all dross. all your tin The tin mixed with silver, that is to say, the wicked among you. בְדִיל is called estejjn [etain] in O.F. [tin].”

“ידי My hand; that is, my smiting (comp. Exod. 9:3). כבור As if it were with soap ; = בור בורית ‘ soap ’; or more correctly, purely (comp. Ps. 18:25). Thy dross. This expression reverts to the former metaphor, thy silver is become dross. בדיליך Thy tin. R. Moses Hakkohen remarks, that the names of the seven kinds of metal are not found in the Bible in the plural ; he forgets בדיליך, which is plural; the singular would be בדילֵך . היחידים, two exceptions: בדיליך ‘thy tin,’ and כספיהם ‘their silver’ (Gen. 42:25). R. Moses Hakkohen does not say the seven kinds of metal, but ועפרת זהב וכסף ונחשת וברזל ובדיל Gold, silver, brass, iron, tin, lead. I. E. makes seven out of these six by applying כסף to silver and mercury (כסף חי)”

“And I will turn my hand upon thee,.... The remnant, according to the election of grace, left in Jerusalem, Isa 1:9 meaning not his afflicting hand, no, not even as a fatherly chastisement; though the Lord sometimes, by such means, purges away the iniquity of his people, as follows; see Isa 27:9 much less his hand of wrath and vengeance, the lighting down of his arm, with the indignation of his anger; but his hand of efficacious grace in conversion, with which he plucks sinners as brands out of the burning; delivers them from the power of Satan; turns their hearts to himself; opens them, to attend unto and understand divine things; breaks them in pieces with the hammer of his word; works grace in them, and carries on the good work in their souls: all which is owing to his mighty hand of grace upon them, and to the exertions of the exceeding greatness of his power towards them. This was accomplished in part in the conversion of a large number of the Jews on the day of Pentecost, and afterwards; and will be more fully accomplished in the latter day, when that people shall turn to the Lord, in consequence of his hand of powerful grace being turned on them. The phrase is used of the display of divine grace and mercy, in Zac 13:7. and purely purge away thy dross; which the Targum rightly interprets of "ungodliness" or wickedness; it means the sins of converted ones, which, at conversion, they are purely purged from; not that sin, as to the being of it, is removed from them; that dwells in them, abides with them; and, like dross, is a heavy burden, a dead weight upon them, and will be while they are in this tabernacle, and makes them groan, being burdened; so far from it, that in their view it rather increases; they see the plague of their own hearts; and such innumerable swarms of corruption they never saw before; sin revives, and they die; but in conversion grace superabounds it, deluges over it, keeps down the force and power of it, so that it has not the dominion; the old man is put off concerning the former conversation, which ceases to be a series, a course of sinning: besides, through the sprinkling of the blood of Christ, which cleanseth from all the dross and filth of sin, the guilt is removed from the conscience, and perfect peace and full pardon take place; all iniquity is caused to pass from them, and they are clothed with change of raiment, the righteousness of Christ, by which they are justified from all things, and are pure, spotless, and without fault before the throne: and take away all thy tin. The Targum also interprets this of iniquity, rendering it, "I will take away all thy sin"; but it is better to understand it of self-righteousness; which, as tin is of more worth than dross, and looks like silver; so this has the appearance of some good in it, and was what the Jews were fond of, trusted in, and depended on, and which they followed after, and endeavoured to establish and hold fast; but this in conversion is all taken away: the Lord, by his Spirit; convinces of the weakness and insufficiency of it, to justify in his sight; shows that it is not a righteousness, and will be of no service in that respect; yea, takes away these filthy rags, and clothes with the righteousness of Christ; causes the soul to drop and renounce its own righteousness, and put on that; and not only to renounce works before conversion, but all after it, as a profession of religion, subjection to Gospel ordinances, and all works, though done in faith, and in a right manner; a glaring instance we have of all this in one of that little remnant, the Apostle Paul, Phi 3:6. Moreover, by "dross" and "tin", or "tins", in the plural number, may be meant persons; wicked and profane men, by the former, who should be put away like dross, Psa 119:119 and self righteous persons, by the latter; who shine like silver, make a show of religion, appear outwardly righteous; but these, as well as the other, should be separated from the people of God, when the precious and the vile should be distinguished.”

“turn . . . hand--not in wrath, but in grace (Zac 13:7), "upon thee," as Isa 1:26-27 show; contrasted with the enemies, of whom He will avenge Himself (Isa 1:24). purely--literally, "as alkali purifies." thy dross--not thy sins, but the sinful persons (Jer 6:29); "enemies" (Isa 1:24); degenerate princes (see on Isa 1:22), intermingled with the elect "remnant" of grace. tin--Hebrew, bedil, here the alloy of lead, tin, &c., separated by smelting from the silver. The pious Bishop Bedell took his motto from this.”

“Isa 1:25 states clearly in what the revenge consisted with which Jehovah was inwardly burdened (innakmah, a cohortative with the ah, indicating internal oppression): "And I will bring my hand over thee, and will smelt out thy dross as with alkali, and will clear away all thy lead." As long as God leaves a person's actions or sufferings alone, His hand, i.e., His acting, is at rest. Bringing the hand over a person signifies a movement of the hand, which has been hitherto at rest, either for the purpose of inflicting judicial punishment upon the person named (Amo 1:8; Jer 6:9; Eze 38:12; Psa 81:15), or else, though this is seldom the case, for the purpose of saving him (Zac 13:7). The reference here is to the divine treatment of Jerusalem, in which punishment and salvation were combined - punishment as the means, salvation as the end. The interposition of Jehovah was, as it were, a smelting, which would sweep away, not indeed Jerusalem itself, but the ungodly in Jerusalem. They are compared to dross, or (as the verb seems to imply) to ore mixed with dross, and, inasmuch as lead is thrown off in the smelting of silver, to such ingredients of lead as Jehovah would speedily and thoroughly remove, "like alkali," i.e., "as if with alkali" (Cabbor, Comparatio decurtata, for C'babbor: for this mode of dropping Beth after Caph, compare Isa 9:3; Lev 22:13, and many other passages). By bedilim (from bâdal, to separate) we are to understand the several pieces of stannum or lead (Note: Plumbum nigrum, says Pliny, n. n. xxiv. 16, is sometimes found alone, and sometimes mixed with silver: ejus qui primus fluic in fornacibus liquor, stannum appellatur. The reference here is to the lead separated from the ore in the process of obtaining pure silver. In the form of powder this dross is called bedil, and the pieces bedilim; whereas ophereth is the name of solid lead, obtained by simply melting down from ore which does not contain silver. The fact that bedil is also apparently used as a name for tin, may be explained in the same way as the homonymy of iron and basalt (Com. on Job 28:2), and of the oak and terebinth. The two metals are called by the same name on account of their having a certain outward resemblance, viz., in softness, pliability, colour, and specific gravity.) in which the silver is contained, and which are separated by smelting, all the baser metals being distinguished from the purer kinds by the fact that they are combustible (i.e., can be oxidized). Both bor, or potash (an alkali obtained from land-plants), and nether, natron (i.e., soda, or natron obtained from the ashes of marine plants, which is also met with in many mineral waters), have been employed from the very earliest times to accelerate the process of smelting, for the purpose of separating a metal from its ore.”
