Numbers 9:5 DBY

³  on the fourteenth day in this month between the two evenings, ye shall hold it at its set time; according to all the rites of it, and according to all the ordinances thereof shall ye hold it.

⁴  And Moses spoke to the children of Israel, that they should hold the passover.

⁵  And they held the passover in the first [month] on the fourteenth day of the month, between the two evenings, in the wilderness of Sinai: according to all that Jehovah had commanded Moses, so did the children of Israel.

⁶  And there were men, who were unclean through the dead body of a man, and could not hold the passover on that day; and they came before Moses and before Aaron on that day.

⁷  And those men said to him, We are unclean by reason of the dead body of a man: why are we kept back, that we may not present the offering of Jehovah at its set time among the children of Israel?
