5:22 two tables of stone. For the third time in Scripture, it is noted that God wrote the ten commandments on two stone tablets (see Exodus 31:18; Deuteronomy 4:13).
6:4 one Lord. This great statement of Israel’s monotheistic faith, intended specifically to set them completely apart from their pantheistic/polytheistic neighbors, actually implies the uni-plural nature of the Godhead. Its declaration amounts to this: “Jehovah our Elohim is one Jehovah.” The name Elohim is of plural form, and often is translated “gods,” when referring to the false gods of the heathen. Yet it is also the great name for the one true God of creation.
6:5 all thy might. This commandment, called by Christ “the first and great commandment” (Matthew 22:37), would certainly–if truly obeyed–have prevented all false religion, all unbelief, indeed all sin.
6:6 in thine heart. The Scriptures are not only to be read and heard, but memorized as well! See also Psalm 119:11, Colossians 3:16, etc.
6:7 unto thy children. Note also Genesis 18:19. God regards the direct education of children by their parents as vitally important, with that education to be founded first of all upon the words of God.
