Verses 1-5: The Command and Observance of the Passover. God commands Moses to instruct Israel to keep the Passover at its appointed time, and the people obey, celebrating it on the fourteenth day of the first month as commanded.
Verses 6-14: Provision for the Unclean and Strangers. Certain men defiled by contact with a dead body could not keep the Passover at the appointed time. God provides an alternative date for them and for those on distant journeys, ensuring inclusion and obedience without impurity.
