Exodus 23:14-17

LEB(i) 14 " 'Three times in the year you will hold a festival for me. 15 You will keep the Feast of Unleavened Bread; for seven days you will eat unleavened bread, as I commanded you at the appointed time, the month of Abib, because in it you came out from Egypt, and no one will* appear before me empty-handed. 16 And you will keep the Feast of Harvest, with the firstfruits of your work, what you sow in the field. And you will keep the Feast of Harvest Gathering when the year goes out, when you gather your work from the field. 17 Three times in the year all your men will appear before the Lord Yahweh.
