Exodus 34:18-24 New American Bible (Revised Edition) (NABRE)
18 You shall keep the festival of Unleavened Bread. For seven days at the appointed time in the month of Abib you are to eat unleavened bread, as I commanded you; for in the month of Abib you came out of Egypt.
19 To me belongs every male that opens the womb among all your livestock, whether in the herd or in the flock. 20 The firstling of a donkey you shall redeem with a lamb; if you do not redeem it, you must break its neck. The firstborn among your sons you shall redeem.
No one shall appear before me empty-handed.
21 Six days you may labor, but on the seventh day you shall rest; even during the seasons of plowing and harvesting you must rest.
22 You shall keep the feast of Weeks with the first fruits of the wheat harvest, likewise, the feast of the Ingathering at the close of the year.[a] 23 Three times a year all your men shall appear before the Lord, the Lord God of Israel. 24 Since I will drive out the nations before you and enlarge your territory, no one will covet your land when you go up three times a year to appear before the Lord, your God.
