Deuteronomy 6:5

Love. The Hebrew word here translated “love” is a general term that also suggests the ideas “desire,” “affection,” “inclination,” the more intimate cleaving of soul to soul.

The believer’s relation to God is based on love (1 John 4:19), and love is the fundamental principle of His law (Mark 12:29, 30). To love perfectly is to obey wholeheartedly (John 14:15; 15:10).

Thine heart. Christianity calls for all that a man is and has — his mind, his affections, and his capacity for action (1 Thess. 5:23). The word here translated “heart” generally refers to the affections, feelings, desires, and will. It is the source of action and the center of thought and feeling (see Ex. 31:6; 36:2; 2 Chron. 9:23; Eccl. 2:23). The word translated “soul” denotes the animating principle in man, the life, but includes also his bodily appetites and desires (see Num. 21:5). It is rendered “appetite” in Prov. 23:2; Eccl. 6:7.

The word translated “might” is from a verb meaning “to increase.” The noun, as here, means “abundance,” and may refer to the things that have accrued to a man in this life.
