16Three times a year all your men are to appear before the LORD your God in the place He will choose: at the Feast of Unleavened Bread, the Feast of Weeks, and the Feast of Tabernacles. No one should appear before the LORD empty-handed.
17Everyone must appear with a gift as he is able, according to the blessing the LORD your God has given you.
— Deuteronomy 16:16-17
