When thou goest, it shall lead thee; when thou sleepest, it shall keep thee; and when thou awakest, it shall talk with thee.
When thou goest, it shall lead thee; when thou sleepest, it shall keep thee; and when thou awakest, it shall talk with thee - i:e., it (the law of God, which every wise parent will inculcate on his child) shall be as a companion conversing with thee, and suggesting subject for meditation, prayer, self-examination, and comfort. It shall lead thee in thy path as a guide (Proverbs 6:23; Psalms 73:24). "It shall keep thee" from Satan, and bad thoughts, and bad dreams, and from all dangers to the body (Proverbs 3:23-24; Psalms 121:3-8). The promise confirms the exhortation.
