Numbers 9:14
And if a stranger shall sojourn among you, and will keep the passover unto the LORD; according to the ordinance of the passover, and according to the manner thereof, so shall he do: ye shall have one ordinance, both for the stranger, and for him that was born in the land.
And if a stranger shall sojourn among you, and will keep the passover unto the Lord,.... Then he must become a proselyte of righteousness, and be circumcised, or otherwise be might not eat of the passover, Exodus 12:48; Ben Gersom interprets this of the second passover, and of a proselyte that was not obliged to the first, he not being then a proselyte, but became one between the first and the second; and so Aben Ezra understands it of a second passover, though he observes, that some say the first is meant:
according to the ordinance of the passover, and according to the manner thereof, so shall he do; according to the several rites and ceremonies, whether of the first or second passover, that an Israelite was obliged to observe, the same a proselyte was to observe, and what they were has been already taken notice of:
ye shall have one ordinance, both for the stranger and for him that was born in the land: for a proselyte, and a native of Israel; see
