Numbers 9:10-13

9:10 “Tell the Israelites, ‘If any of you or of your posterity become ceremonially defiled by touching a dead body, or are on a journey far away, then he may observe the Passover to the Lord. 9:11 They may observe it on the fourteenth day of the second month at twilight; they are to eat it with bread made without yeast and with bitter herbs. 9:12 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.

9:13 But the man who is ceremonially clean, and was not on a journey, and fails to keep the Passover, that person must be cut off from his people. Because he did not bring the Lord’s offering at its appointed time, that man must bear his sin.

Matthew 5:23-24

5:23 So then, if you bring your gift to the altar and there remember that your brother has something against you, 5:24 leave your gift there in front of the altar. First go and be reconciled to your brother and then come and present your gift.
