Numbers 9:2-7

CAB(i) 2 Speak, and let the children of Israel keep the Passover in its season. 3 On the fourteenth day of the first month at evening, you shall keep it in its season; you shall keep it according to its law, and according to its ordinance. 4 And Moses ordered the children of Israel to sacrifice the Passover, 5 on the fourteenth day of the first month in the Wilderness of Sinai, as the Lord appointed Moses, so the children of Israel did. 6 And there came men who were unclean by reason of a dead body, and they were not able to keep the Passover on that day; and they came before Moses and Aaron on that day. 7 And those men said to Moses, We are unclean by reason of the dead body of a man: shall we therefore fail to offer the gift to the Lord in its season in the midst of the children of Israel?
