Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for an house: In the tenth day of this month - In after times they began their preparation on the thirteenth day or day before the Passover, which was not celebrated till the fourteenth day, see Exodus 12:6 : but on the present occasion, as this was their first passover, they probably required more time to get ready in; as a state of very great confusion must have prevailed at this time. Mr. Ainsworth remarks that on this day the Israelites did afterwards go through Jordan into the land of Canaan; Joshua 4:19. And Christ, our Paschal Lamb, on this day entered Jerusalem, riding on an ass; the people bearing palm branches, and crying, Hosanna, John 12:1, John 12:12, John 12:13, etc.: and in him this type was truly fulfilled.
A lamb - The original word שה seh signifies the young of sheep and of goats, and may be indifferently translated either lamb or kid. See Exodus 12:5.
A lamb for a house - The whole host of Israel was divided into twelve tribes, these tribes into families, the families into houses, and the houses into particular persons; Numbers 1, Joshua 7:14 - Ainsworth.
