Three times in a year shall all thy males appear before the LORD thy God in the place which he shall choose; in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles: and they shall not appear before the LORD empty:
Once a year, all your male family members should go to the special place chosen by God during three celebrations - the festival of unleavened bread, the festival of weeks, and the festival of tabernacles. They must not go empty-handed; they should bring offerings with them.
