Exodus 34:18–25

¹⁸“You will keep the Feast of Unleavened Bread. Seven days you will eat unleavened bread, which I commanded you, at the appointed time of the month of Abib, for in the month of Abib you came out from Egypt. ¹⁹Every first offspring of a womb is for me—all of your male livestock, the first offspring of cattle and small livestock. ²⁰But the first offspring of a donkey you will redeem with small livestock, and if you will not redeem it, you will break its neck. Every firstborn of your sons you will redeem, and you will not appear before me empty-handed. ²¹Six days you will work, and on the seventh day you will rest; in the time of plowing and in the time of harvest you will rest. ²²And you yourself^j will observe the Feast of Weeks—the firstfruits of the wheat harvest—and the Feast of Harvest Gathering at the turn of the year. ²³Three times in the year all your males will appear before the Lord, Yahweh, the God of Israel, ²⁴because I will evict nations before you, and I will enlarge your territory, and no one will covet your land when you go up to appear before Yahweh your God three times in the year.

²⁵“You will not slaughter the blood of my sacrifice on food with yeast, and the sacrifice of the Feast of the Passover will not stay overnight to the morning.
