I sat in the surgery feeling so sick
A nurse was coming with a needle to give me a prick
Now roll up your sleeve and give me your arm
This won't hurt and will do you no harm
She came at me like a devil with a smile of a saint
The sight of that needle made me quite faint
She searched for a vein to stick it right in
Launched it like a lance right it into my skin
I closed my eyes as I felt it jag
And my foot flew out and kicked her on the leg
I could have reached up and give her neck a throttle
But I bore it without screaming until my blood filled a bottle
Now; said the nurse; I'll send it away for a test
Go home; for you look pale and have a wee rest
When I made it in through my door I went straight up to bed
And below the blankets these thoughts came into my head
They might find something wrong with the blood taken from me
But pure was the blood that was shed for me on a tree
Sin cleansing blood from the innocent One
The sacrificial Lamb and God's only Son
Blood with no impurity; deep crimson red
Staining Calvary Hill from my Saviour who bled
Blood offered for me; the purest and best
No fault in it the Father could test
And accepted by Him as an offering for my sin
As its cleansing power washed me from within
Jesus gave all of His blood and did not complain
The loss of its flowing was for my gain
Blood from me may test with faults and impure
The results I get will tell me for sure
But one thing I know; and of it; so confident I am
That my sins are blotted out by the blood of the Lamb
