Deuteronomy 31:12 (KJV)

And Moses commanded them, saying, At the end of every seven years, in the solemnity of the year of release, in the feast of tabernacles,

When all Israel is come to appear before the Lord thy God in the place which he shall choose, thou shalt read this law before all Israel in their hearing.

Gather the people together, men, and women, and children, and thy stranger that is within thy gates, that they may hear, and that they may learn, and fear the Lord your God, and observe to do all the words of this law:

And that their children, which have not known any thing, may hear, and learn to fear the Lord your God, as long as ye live in the land whither ye go over Jordan to possess it.

And the Lord said unto Moses, Behold, thy days approach that thou must die: call Joshua, and present yourselves in the tabernacle of the congregation, that I may give him a charge. And Moses and Joshua went, and presented themselves in the tabernacle of the congregation.
