CLV(i)
25 It will come to be when you are entering to the land which Yahweh is giving to you just as He spoke, then you will observe this service.
26 And it will come to be when your sons are saying to you: What is this service to you?
27 Then you will say: It is the sacrifice of passover to Yahweh, Who passed over the houses of the sons of Israel in Egypt, when He struck the Egyptians, yet our households He rescued. So the people bowed their heads and bowed themselves down.
