Numbers 9:4 DBY

²  Let the children of Israel also hold the passover at its set time;

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.
