Exodus 12:25-27

CAB(i) 25 And if you should enter into the land which the Lord shall give you, as He has spoken, keep this service. 26 And it shall come to pass, if your sons say to you, What is this service? 27 That you shall say to them, This Passover is a sacrifice to the Lord, as He defended the houses of the children of Israel in Egypt, when He struck the Egyptians, but delivered our houses.
