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:

11 when all men of Israel shall come together, that they appear in the sight of their Lord God, in the place which the Lord choose, thou shalt read the words of this law before all Israel, while they hear, (when all the people of Israel shall come together, so that they can come before the Lord their God, in the place which the Lord shall choose, thou shalt read the words of this law before all Israel, while they hear,)

12 and while all the people is gathered together, as well to men, as to women, to little children, and to comelings that be within thy gates; that they hear, and learn, and dread your Lord God, and keep and [ful]fill all the words of this law; (and while all the people is gathered together, men and women, and little children, and the newcomers who be within thy gates; so that they can listen, and learn, and fear the Lord your God/and revere the Lord your God, and obey and fulfill all the words of this law;)

13 also that the sons of them, that now know not, may hear, and that they dread their Lord God in all days in which they live in the land to which ye shall go to get, when (the) Jordan is passed. (and also so that their children, who now do not know, can listen, and learn to fear the Lord their God/and learn to revere the Lord their God, in all the days in which they live in the land to which ye shall go to get, after that ye have crossed over the Jordan River.)

14 And the Lord said to Moses, Lo! the days of thy death be nigh; call thou Joshua, and stand ye in the tabernacle of witnessing, that I command to him (and stand ye together in the Tabernacle of the Witnessing, so that I can give him his charge, or his commission). Therefore Moses and Joshua went, and they stood in the tabernacle of (the) witnessing;

15 and the Lord appeared there in a pillar of cloud, that stood in the entering of the tabernacle (that stood at the entrance to the Tabernacle).
