Well, we all remember Moses on the banks of the river
He said "Pharaoh, you've got to let my people go.
You don't want me to have to tell you this ten times over--
Denial ain't just a river, you know"

And we all remember Pharaoh, he just wouldn't do it
So the plagues they came upon Egypt one by one
His heart was hard and the other nine just couldn't move it
So the last was the worst: the death of the firstborn son

But the Lord, he gave to Moses a word for the people
He said their firstborn sons could live to see another day
"Put the blood of a lamb on the doorway and death will pass right over"
That night all of the children of Israel prayed,

"Lord, let your judgment Passover us
Lord, let your love hover near
Don't let your sweet mercy Passover us
Let this blood cover over us here"
So the years went by and the people they whined and they wandered
And only sacrifice atoned for the sins of the land
So you see the priest he placed upon the holy altar
The body of a spotless lamb
And he prayed
