Deuteronomy 31:9-11 - The Reading Of The Law
9 And Moses wrote this law and delivered it unto the priests, the sons of Levi, which bare the ark of the covenant of the LORD, and unto all the elders of Israel, 10 and commanded them, saying, "At the end of seven years, in the time of the free year, in the feast of the tabernacles, 11 when all Israel is come to appear before the LORD thy God, in the place which he hath chosen: see that thou read this law before all Israel in their ears.
