'Sweat' in the Bible

By the sweat of your brow you will eat food until you return to the ground, for out of it you were taken; for you are dust, and to dust you will return."

Linen turbans will be on their heads and linen undergarments will be around their waists; they must not bind themselves with anything that causes sweat.

And in his anguish he prayed more earnestly, and his sweat was like drops of blood falling to the ground.]
