Numbers 9:8-12
English Standard Version
Chapter 9
8And Moses said to them, "Wait, that I may hear what the Lord will command concerning you."
9The Lord spoke to Moses, saying,
10"Speak to the people of Israel, saying, If any one of you or of your descendants is unclean through touching a dead body, or is on a long journey, he shall still keep the Passover to the Lord.
11In the second month on the fourteenth day at twilight they shall keep it. They shall eat it with unleavened bread and bitter herbs.
12They shall leave none of it until the morning, nor break any of its bones; according to all the statute for the Passover they shall keep it.
