Exodus 34:26

²⁴For when I shall have cast out the nations before thy face, and shall have enlarged thy coasts, no one shall desire thy land, whenever thou mayest go up to appear before the Lord thy God, three times in the year.

²⁵Thou shalt not offer the blood of my sacrifices with leaven, neither shall the sacrifices of the feast of the Passover remain till the morning.

— Exodus 34:26 —

²⁷And the Lord said to Moses, Write these words for thyself, for on these words I have established a covenant with thee and with Israel.

²⁸And Moses was there before the Lord forty days, and forty nights; he did not eat bread, and he did not drink water; and he wrote upon the tables these words of the covenant, the ten sayings.
