Exodus 34:23-25

Darby Translation

²³ Thrice in the year shall all thy males appear before the Lord Jehovah, the God of Israel.

²⁴ For I will dispossess the nations before thee, and enlarge thy border, and no man shall desire thy land, when thou goest up to appear before the face of Jehovah thy God thrice in the year.

²⁵ —Thou shalt not offer the blood of my sacrifice with leaven; neither shall the sacrifice of the feast of the passover be left over night until the morning.
