Exodus 12:21-22 Then Moses summoned all the elders of Israel and said to them, "Go at once and select the animals for your families and slaughter the Passover lamb. (After Moses' last confrontation with Pharaoh, Moses had instructed the people that on the tenth day of the month which the Lord said would now be the first month of their year, occurring sometime in our March or April, they were to choose an unblemished lamb from their flock, bring it out of the field into their immediate supervision, and give it careful attention and care in preparation for its sacrifice that would happen on the fourteenth day. As the family built a special bond with the innocent little lamb as they gave it special, nurturing treatment, the Lord wanted to make sure His people learned and understood the staggering cost of sin and disobedience, that redemption and deliverance only come through the shedding of innocent blood, that sin causes death, and that redemption requires death.) Take a bunch of hyssop, dip it into the blood in the basin and put some of the blood on the top and on both sides of the doorframe. (The word basin may refer to the threshold of the home or it may be a vessel into which the blood is drained. The hyssop branch is probably the same plant that the soldiers used to offer Jesus a drink while He hung on the cross ready to shed His blood. With the lamb's blood now covering the doorway into their home, the Israelites were protected from God's judgment and also saved by God's deliverance.) None of you shall go out of the door of your house until morning." (Only under the covering of the blood of the lamb are the Israelites protected from judgment and destruction. Once they stepped outside of that blood covering, they would be lost. If we refuse the covering the Lord has provided, we are in danger of God's judgment. Only with the covering of the blood of the Lamb, Jesus Christ's Own shed blood, are we protected from judgment and destruction today.)
