Passover at Sinai. This, as being kept in the first month, was prior in time to the numbering of Numbers 1:1 ff, and to the other events narrated in this book. It is, however, recorded here as introductory to the ordinance of Numbers 9:6-14 in this chapter respecting the supplementary Passover; the observance of which was one of the last occurrences during the halt at Sinai.
In some details, the present Passover differed both from that kept at the Exodus itself and from all subsequent Passovers. For example, the direction of Exodus 12:22 could not be carried out in the letter while the people were dwelling in tents; and may be regarded as superseded by Leviticus 17:3-6 (compare Deuteronomy 16:5 ff).
In other points, such as how many lambs would be wanted, how the blood of the Paschal victims could be sprinkled upon the altar in the time specified, etc., the administrators of the Law of Moses would here, as elsewhere, have, from the nature of the case, power to order what might be requisite to carry the law into effect.
