Therefore speak unto them, and say unto them, Thus saith the Lord GOD; Every man of the house of Israel that setteth up his idols in his heart, and putteth the stumblingblock of his iniquity before his face, and cometh to the prophet; I the LORD will answer him that cometh according to the multitude of his idols;
Every man ... that setteth up his idols in his heart ... and cometh - and yet cometh, feigning himself to be a true worshipper of Yahweh.
I the Lord will answer him that cometh х baa' (H935)] so the margin Hebrew reads But the text I the Lord will answer him that cometh, х baa' (H935)] - so the margin Hebrew reads. But the text Hebrew reading is, 'I the Lord will answer according to it [baah] according to the multitude of his idols;' the anticipative clause with the pronoun not being pleonastic, but increasing the emphasis of the following clause with the noun. "I will answer" - literally, reflexively. 'I will myself (or for myself) answer him.'
According to the multitude of his idols - thus "answering a fool according to his folly;" making the sinner's sin his punishment; retributive justice (Proverbs 1:31; Proverbs 26:4).
