What hath my beloved to do in mine house, seeing she hath wrought lewdness with many, and the holy flesh is passed from thee? when thou doest evil, then thou rejoicest.
My beloved - my elect people, Judea: this aggravates their ingratitude (Jeremiah 12:7).
She hath wrought lewdness with many - (Ezekiel 16:25); rather, 'that great (or manifold) enormity;' literally, the enormity, the manifold-namely, their idolatry, which made their worship of God in the temple a mockery (cf. Jeremiah 7:10; Ezekiel 23:39). (Henderson.)
The holy flesh is passed for thee - (Haggai 2:12-14; Titus 1:15), namely, the sacrifices, which, through the guilt of the Jews, were no longer holy - i:e., acceptable to God. The sacrifices on which they relied will therefore no longer protect them. Judah is represented as a priest's wife, who, by adultery, has forfeited her share in the flesh of the sacrifices, and yet boasts of her prerogative at the very same time (Horsley).
When thou doest evil, then thou rejoicest - literally, 'when thy evil' (is at hand). Piscator translates, 'When thy calamity is at hand (according to God's threats), thou gloriest' (against God, instead of humbling thyself). The English version is best (cf. Proverbs 2:14. Contrast 1 Corinthians 13:6, "Rejoiceth not in iniquity").
