1
Christ, our Redeemer, died on the cross
Died for the sinner, paid all his due;
All who receive Him need never fear,
Yes, He will pass over you
2
Chiefest of sinners Jesus can save,
As He has promised, so will He do;
O sinner, hear Him, trust in His word.
Then He will pass, will pass over you.
3
Judgment is coming, all will be there,
Who have rejected, who have refused,
O sinner, hasten, let Jesus in,
Then God will pass, will pass over you
4
O what compassion, O boundless love,
Jesus hath power, Jesus is true;
All who believe are safe from the storm,
O He will pass, will pass over you.
REFRAIN
When I see the blood
When I see the blood
When I see the blood
I will pass, I will pass over you

Sometimes I love to hear a good ol' Baptist church pianist just go to town on a song that might otherwise be kind of boring...

Exodus 12:1 And the Lord spake unto Moses and Aaron in the land of Egypt saying, 2 This month shall be unto you the beginning of months: it shall be the first month of the year to you. 3 Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for an house... 5 Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats: 6 And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening. 7 And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it. 8 And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it... 11 And thus shall ye eat it; with your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste: it is the Lord's passover. 12 For I will pass through the land of Egypt this night, and will smite all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I am the Lord. 13 And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt. 14 And this day shall be unto you for a memorial; and ye shall keep it a feast to the Lord throughout your generations; ye shall keep it a feast by an ordinance for ever... 21 Then Moses called for all the elders of Israel, and said unto them, Draw out and take you a lamb according to your families, and kill the passover. 22 And ye shall take a bunch of hyssop, and dip it in the blood that is in the bason, and strike the lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning. 23 For the Lord will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side posts, the Lord will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you. 24 And ye shall observe this thing for an ordinance to thee and to thy sons for ever. 25 And it shall come to pass, when ye be come to the land which the Lord will give you, according as he hath promised, that ye shall keep this service. 26 And it shall come to pass, when your children shall say unto you, What mean ye by this service? 27 That ye shall say, It is the sacrifice of the Lord's passover, who passed over the houses of the children of Israel in Egypt, when he smote the Egyptians, and delivered our houses. And the people bowed the head and worshipped. 28 And the children of Israel went away, and did as the Lord had commanded Moses and Aaron, so did they. 29 And it came to pass, that at midnight the Lord smote all the firstborn in the land of Egypt, from the firstborn of Pharaoh that sat on his throne unto the firstborn of the captive that was in the dungeon; and all the firstborn of cattle. 30 And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt; for there was not a house where there was not one dead. 31 And he called for Moses and Aaron by night, and said, Rise up, and get you forth from among my people, both ye and the children of Israel; and go, serve the Lord, as ye have said... 37 And the children of Israel journeyed from Rameses to Succoth, about six hundred thousand on foot that were men, beside children. 38 And a mixed multitude went up also with them; and flocks, and herds, even very much cattle... 40 Now the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years. 41 And it came to pass at the end of the four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of the Lord went out from the land of Egypt. 42 It is a night to be much observed unto the Lord for bringing them out from the land of Egypt: this is that night of the Lord to be observed of all the children of Israel in their generations.
