Exodus 34:23-25

World English Bible

²³ Three times in the year all your males shall appear before the Lord Yahweh, the God of Israel. ²⁴ For I will drive out nations before you and enlarge your borders; neither shall any man desire your land when you go up to appear before Yahweh, your God, three times in the year.

²⁵ “You shall not offer the blood of my sacrifice with leavened bread. The sacrifice of the feast of the Passover shall not be left to the morning.
