"Tell all the congregation of Israel that on the tenth day of this month they shall take every man a lamb according to their fathers' houses, a lamb for a household; and if the household is too small for a lamb, then a man and his neighbor next to his house shall take according to the number of persons; according to what each can eat you shall make your count for the lamb. Your lamb shall be without blemish, a male a year old; you shall take it from the sheep or from the goats; and you shall keep it until the fourteenth day of this month, when the whole assembly of the congregation of Israel shall kill their lambs in the evening. Then they shall take some of the blood, and put it on the two doorposts and the lintel of the houses in which they eat them." Exodus 12: 3-7
The blood of the lamb that was slain on the night of the Passover protected the people of Israel from the final, and most gruesome, of the plagues to strike Egypt. The Angel of Death passed over the houses of the faithful because the doorposts and lintels were washed in the blood of the lamb. We who are washed in the Blood of the Lamb of God receive the same gift. Death has no dominion over us; and we shall be afraid.
Just a thought.
