Numbers 9:5-7

New King James Version

⁵ And ^(A)they kept the Passover on the fourteenth day of the first month, at twilight, in the Wilderness of Sinai; according to all that the Lord commanded Moses, so the children of Israel did.

⁶ Now there were certain men who were ^(B)defiled by a human corpse, so that they could not keep the Passover on that day; ^(C)and they came before Moses and Aaron that day. ⁷ And those men said to him, “We became defiled by a human corpse. Why are we kept from presenting the offering of the Lord at its appointed time among the children of Israel?”
