i read all your messages about this "keep Your eyes on the prize/keep your hands on the plot"

I am not an english speaking person so i tried to note the lyrics after the version of the CD "hard travelling" from pete seeger (the title on the cover is "hold on")

i heard this:

oah noah let me come in
doors are locked and the wind got in
Keep your hand on that plow, hold on
Oh Lord, Oh Lord, keep your hand on that plow, hold on.

Mary wore three links of chain
Every link was Jesus name
Keep your hand on that plow, hold on
Oh Lord, Oh Lord, keep your hand on that plow, hold on.

God gave Noah the rainbow sign
No more water but fire next time
Keep your hand on that plow, hold on
Oh Lord, Oh Lord, keep your hand on that plow, hold on.

United nations make a chain
every link is Peter's name
Keep your hand on that plow, hold on
Oh Lord, Oh Lord, keep your hand on that plow, hold on.

freedom's name is mighty sweet
it can quite park on our knee??
Keep your hand on that plow, hold on
Oh Lord, Oh Lord, keep your hand on that plow, hold on.

Many Good Men have fought and died
So we could be here side by side
Keep your hand on that plow, hold on
Oh Lord, Oh Lord, keep your hand on that plow, hold on.

Freedom's name is mighty sweet
it can quite park on our knee??
Keep your hand on that plow, hold on
Oh Lord, Oh Lord, keep your hand on that plow, hold on.

Keep your hand on the gospel plow
Iwouldn't take nothing from my journey now
Keep your hand on that plow, hold on
Oh Lord, Oh Lord, keep your hand on that plow, hold on.

i am not quite sure of the sentence with an interrogation mark(can someone help me?)
but i hope this will help. If it is false correct me
