Read Numbers 9:13 Using Other Translations
But the man that is clean, and is not in a journey, and forbeareth to keep the passover, even the same soul shall be cut off from among his people: because he brought not the offering of the LORD in his appointed season, that man shall bear his sin.
But if anyone who is clean and is not on a journey fails to keep the Passover, that person shall be cut off from his people because he did not bring the LORD's offering at its appointed time; that man shall bear his sin.
“But those who neglect to celebrate the Passover at the regular time, even though they are ceremonially clean and not away on a trip, will be cut off from the community of Israel. If they fail to present the LORD ’s offering at the proper time, they will suffer the consequences of their guilt.
