Deuteronomy 31:13 Meaning and Commentary

Deuteronomy 31:13

And [that] their children, which have not known [anything],
&c.] Of God and of his law and of their duty to God, to their parents, and the rest of their fellow creatures:

may hear, and learn to fear the Lord your God;
hear the law of God, learn the meaning of it, and so be brought up in the fear, nurture, and admonition of the Lord, and serve him their Creator in the days of their youth:

as long as ye live in the land whither ye go over Jordan to possess
it;
this being a means to continue the fear, service, and worship of God in their posterity, and so of their long continuance in the land of Canaan.

Deuteronomy 31:13 In-Context

11 when all Israel comes to appear before the Lord your God at the place that he will choose, you shall read this law before all Israel in their hearing.
12 Assemble the people—men, women, and children, as well as the aliens residing in your towns—so that they may hear and learn to fear the Lord your God and to observe diligently all the words of this law,
13 and so that their children, who have not known it, may hear and learn to fear the Lord your God, as long as you live in the land that you are crossing over the Jordan to possess."
14 The Lord said to Moses, "Your time to die is near; call Joshua and present yourselves in the tent of meeting, so that I may commission him." So Moses and Joshua went and presented themselves in the tent of meeting,
15 and the Lord appeared at the tent in a pillar of cloud; the pillar of cloud stood at the entrance to the tent.
