Numbers 9:2-7

VIN(i) 2 "Let the Israelites observe the Passover at its appointed time. 3 On the fourteenth day of this month, at twilight at its appointed time, you shall observe it. Keep it according to all its decrees and laws. 4 So Moses told the Israelites to celebrate the Passover. 5 They celebrated it on the fourteenth day of the first month at dusk while they were in the Desert of Sinai. The Israelites did everything as the LORD commanded Moses. 6 But there were men who couldn't observe the Passover that day on account of a corpse. They approached Moses and Aaron that day. 7 And those men said to him, "Although we are unclean by a dead person, why are we hindered from presenting the offering of the LORD at its appointed time in the midst of the Israelites?"
