Bind them upon thy fingers - See on Proverbs 3:3 (note).

Bind them upon thy fingers,.... Let the above words and doctrines be as ready and familiar as if they were at the fingers' ends; or let them be always fresh in memory, as a piece of thread is tied about the fingers, to put in mind of anything to be done; or let them be as rings upon the fingers, both memorial and ornamental: or put into practice the things taught and commanded; the fingers being the instruments of action, and especially of doing things nicely and accurately;
write them upon the table of thine heart; that they may be strong in the memory, deep in the affection, and abiding in the understanding and will; see Proverbs 3:3.

Bind . . . fingers--as inscriptions on rings.

Bind them - As a ring which is continually in a man's eye.
