When thou goest, it shall lead thee,.... The law of God taught by parents; this directs man in the path of duty and business of life; teaches him what way to shun, and which to walk in; it leads out of the paths of sin, and into the way in which he should go, which is most conducive to his good, and to the glory of God; it will lead him safely, so that he shall not stumble, Pr 3:3;when thou sleepest, it shall keep thee; from terrifying dreams, evil spirits, dangers by fire or thieves; one that observes it conscientiously may lie down and sleep, secure of the guardianship of divine Providence, and not fear any evil; or "shall watch over thee" in the night season;and [when] thou awakest, it shall talk with thee; familiarly; and instruct what to do, and how to behave the day following; or "it shall go out with thee" , into the fields for a morning's walk, and assist in meditation.
Jarchi interprets this of sleeping by death, and of awaking at the resurrection of the dead. Kyle rmvt "excubabit apud te", Cocceius; "excubias aget super te", Michaelis, Schultens.
