And he answering said, thou shalt love the Lord thy God,.... This was part of their phylacteries, which they recited every day; See Gill on Matthew 22:37, Matthew 22:39, Mark 12:28, Mark 12:29
Thou shalt, &c.--the answer Christ Himself gave to another lawyer. (See on Mark 12:29-33).
Thou shalt love the Lord thy God - That is, thou shalt unite all the faculties of thy soul to render him the most intelligent and sincere, the most affectionate and resolute service. We may safely rest in this general sense of these important words, if we are not able to fix the particular meaning of every single word. If we desire to do this, perhaps the heart, which is a general expression, may be explained by the three following, With all thy soul, with the warmest affection, with all thy strength, the most vigorous efforts of thy will, and with all thy mind or understanding, in the most wise and reasonable manner thou canst; thy understanding guiding thy will and affections. Deuteronomy 6:5; Leviticus 19:18.
