Jeremiah 35:16

Because the son of Jonadab the son of Rechab
Here we have the contrast between the Rechabites and the Israelites; the obedience of the one, and the disobedience of the other; the design of which is to aggravate and expose the sin of the Jews, since the former have performed the commandment of their father, which he commanded
them;
that particular commandment of not drinking wine, which they had never once violated in such a course of time; nor could they now be prevailed upon, even by the prophet himself, to do it: but this people hath not hearkened unto me;
the Lord their God, their father that bought them, made them, and established them. Gross ingratitude! ( Deuteronomy 32:6 ) .
