Exodus 12:42-44

Darby Translation

⁴² It is a night of observance to Jehovah, because of their being brought out from the land of Egypt: that same night is an observance to Jehovah for all the children of Israel in their generations.

⁴³ And Jehovah said to Moses and Aaron, This is the ordinance of the passover: No stranger shall eat of it;

⁴⁴ but every man's bondman that is bought for money—let him be circumcised: then shall he eat it.
