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.
