Deuteronomy 6:6-7

Amplified Bible

⁶ These words, which I am commanding you today, shall be [written] on your heart and mind. ⁷ You shall teach them diligently to your ^[a]children [impressing God’s precepts on their minds and penetrating their hearts with His truths] and shall speak of them when you sit in your house and when you walk on the road and when you lie down and when you get up.
