Deuteronomy 6:6

And these words, which I command thee this day,.... To hearken to, observe, and take notice of, that God is one, and is to be loved in the strongest manner that possibly can be:

shall be in thine heart; on the table of the heart, as the Targum of Jonathan; see 2 Corinthians 3:3, be cordially received, have a place in the affections of the heart, and be retained in mind and memory.
