“The Israelites are to observe ¹  the Passover ²  at its appointed time. ³ 

So Moses instructed ¹  the Israelites to observe ²  the Passover.

“‘On the fourteenth day of the first month is the Lord’s Passover.

If a resident foreigner lives ¹  among you and wants to keep ²  the Passover to the Lord, he must do so according to the statute of the Passover, and according to its custom. You must have ³  the same ⁴  statute for the resident foreigner ⁵  and for the one who was born in the land.’”

They must not leave any of it until morning, nor break any of its bones; they must observe it in accordance with every statute of the Passover.

And they observed the Passover ¹  on the fourteenth day of the first month at twilight in the wilderness of Sinai; in accordance with all that the Lord had commanded Moses, so the Israelites did.

It happened that some men ¹  who were ceremonially defiled ²  by the dead body of a man ³  could not keep ⁴  the Passover on that day, so they came before Moses and before Aaron on that day.

“Tell the Israelites, ‘If any ¹  of you or of your posterity become ceremonially defiled by touching a dead body, or are on a journey far away, then he may ²  observe the Passover to the Lord.

But ¹  the man who is ceremonially clean, and was not on a journey, and fails ²  to keep the Passover, that person must be cut off from his people. ³  Because he did not bring the Lord’s offering at its appointed time, that man must bear his sin. ⁴ 

They departed from Rameses in the first month, on the fifteenth day of the first month; on the day ¹  after the Passover the Israelites went out defiantly ²  in plain sight ³  of all the Egyptians.
