The lamb was to be eaten with bitter herbs, as pointing back to the bitterness of the bondage in Egypt. So when we feed upon Christ, it should be with contrition of heart, because of our sins. The use of unleavened bread also was significant. It was expressly enjoined in the law of the Passover, and as strictly observed by the Jews in their practice, that no leaven should be found in their houses during the feast. In like manner the leaven of sin must be put away from all who would receive life and nourishment from Christ. So Paul writes to the Corinthian church, “Purge out therefore the old leaven, that ye may be a new lump.... For even Christ our Passover is sacrificed for us: therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.” 1 Corinthians 5:7, 8.

Before obtaining freedom, the bondmen must show their faith in the great deliverance about to be accomplished. The token of blood must be placed upon their houses, and they must separate themselves and their families from the Egyptians, and gather within their own dwellings. Had the Israelites disregarded in any particular the directions given them, had they neglected to separate their children from the Egyptians, had they slain the lamb, but failed to strike the doorpost with blood, or had any gone out of their houses, they would not have been secure. They might have honestly believed that they had done all that was necessary, but their sincerity would not have saved them. All who failed to heed the Lord’s directions would lose their first-born by the hand of the destroyer. (PP 278.2) MC VC
