Proverbs 6:21

Bind them continually upon thine heart
Not upon the head or arm, as the words of the law were to be bound, ( Deuteronomy 6:3 ) ; to which there seems to be an allusion; and which may confirm the sense of the words given, that this respects the law of God itself, and the precepts of it, instructed in by parents; but they should be bound upon the heart, and have an abiding place in the understanding, affections, memory, and will; [and] tie them about thy neck;
as an ornament, instead of a necklace of pearl, or chains of gold; they should be so far from being thought burdensome and troublesome, that they should be reckoned comely and graceful; see ( Proverbs 1:9 ) ( Proverbs 3:3 Proverbs 3:22 ) .
