Exodus 34:23-25

New Living Translation

²³ Three times each year every man in Israel must appear before the Sovereign, the Lord, the God of Israel. ²⁴ I will drive out the other nations ahead of you and expand your territory, so no one will covet and conquer your land while you appear before the Lord your God three times each year.

²⁵ “You must not offer the blood of my sacrificial offerings together with any baked goods containing yeast. And none of the meat of the Passover sacrifice may be kept over until the next morning.
