In this chapter the command for keeping the passover is repeated, and it was accordingly kept, Nu 9:1-5; but some persons being defiled and disqualified for observing it, Moses inquires of the Lord, on their solicitation, what should be done in such a case, Nu 9:6-8; when it was ordered to be kept by such, and those on journeys, on the fourteenth day of the second month, but not by others, who were to observe it according to its first appointment, Nu 9:9-14; and an account is given of the appearance of the cloud by day, and fire by night, upon the tabernacle, which directed the children of Israel when to journey, and when to pitch their tents, Nu 9:15-23.
