20Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.
21Then Moses called for all the elders of Israel, and said unto them, Draw out, and take you lambs according to your families, and kill the passover.
22And ye shall take a bunch of hyssop, and dip it in the blood that is in the basin, and strike the lintel and the two side-posts with the blood that is in the basin; and none of you shall go out of the door of his house until the morning.
23For Jehovah will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side-posts, Jehovah will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you.
24And ye shall observe this thing for an ordinance to thee and to thy sons for ever.
25And it shall come to pass, when ye are come to the land which Jehovah will give you, according as he hath promised, that ye shall keep this service.
26And it shall come to pass, when your children shall say unto you, What mean ye by this service?
