And when thy son asketh thee in time to come,.... Or "tomorrow" (x); that is, in later times, as Jarchi interprets it; any time after this, and particularly after they were come into the land of Canaan, when the several laws, statutes, and ordinances appointed, would take place and be obeyed: what mean the testimonies, and the statutes, and the judgments, which the Lord our God hath commanded you? what is the reason of the various rites, customs, and usages, the observance of which is directed to, such as the feasts of passover, pentecost, tabernacles, sacrifices, and other duties of religion? (x) "cras", V. L. Pagninus, Montanus.
