What action did God command His people regarding lambs during Passover?

The correct response highlights the significance of the lamb's sacrifice during the Passover event as described in the Hebrew Bible. God instructed the Israelites to select a lamb, sacrifice it, and use its blood to mark their doorposts. This act signified obedience to God's command and served as a signal to spare the firstborns of the Israelites during the final plague in Egypt, thereby providing divine protection.

The blood of the lamb acted as a powerful symbol of salvation and deliverance from oppression, marking the beginning of the Israelites' exodus from slavery. This ritual became a foundational practice within Jewish tradition, commemorating God's faithfulness and the liberation of His people.

In contrast, the other choices do not accurately reflect the biblical narrative surrounding Passover. Offering a lamb without consuming it does not capture the essence of the sacrificial practice, while buying a lamb from the market overlooks the deeper spiritual implications of sacrifice. Keeping a lamb as a pet also misses the critical element of sacrifice as a means of protection and remembrance of God's actions on behalf of the Israelites.
