Matthew Poole and continuators on Isaiah 31:7

7. For in that day every Man shall cast away his idols of silver, and his idols of gold, which your own hands have made unto you for a sin .

For when the Assyrian shall invade your Land, you shall find the vanity of those Idols, to which you have trusted; and therefore shall cast them away with indignation, and be forced to seek to Me for Help. So this is added, as an Argument to perswade them to practise his Counsel of turning to God.

Which you have made as Instruments of your sin of Idolatry. Or, Which your sinful hands (by a common Hebraisme, called hands of sin) have made for you. Or, the sin (as an Idol is called, Deut, 9. 21:) which your hands have made for you. So there is onely a Transposition of one Word, which is very usual in the Hebrew Text.

Marginal references: Chap. 2. 20. & 30. 22.; Heb. the idols of his gold.
