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" F4;
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.
