Deuteronomy 7:4
For they will turn away thy son from following me, that they may serve other gods: so will the anger of the LORD be kindled against you, and destroy thee suddenly.
For they will turn away thy son from following me,.... From the pure worship of God, his word, statutes, and ordinances:
that they may serve other gods; worship their idols; that is, the daughters of Heathens, married to the sons of Israelites, would entice them from the worship of the true God to idolatry; so the Targum of Jonathan; as Solomon's wives drew him aside: or "he will turn away thy son" {d}; meaning, as Jarchi observes, that the son of an Heathen, that marries the daughter of an Israelite, will turn away the son born of her to idolatry, called here the grandfather's son; though Aben Ezra says this respects the son mentioned in the preceding verse, that is, the son married to an Heathen woman, and not to a son born in such marriage:
so will the anger of the LORD be kindled against you, and destroy thee suddenly; by some immediate judgment striking dead at once; there being nothing more provoking to God than idolatry, that being directly contrary to his being, nature, perfections, honour, and glory, of which he is jealous.
