'Sweat' in the Bible

You will eat bread by the sweat of your browuntil you return to the ground,since you were taken from it.For you are dust,and you will return to dust.”

They must wear linen turbans on their heads and linen undergarments around their waists. They are not to put on anything that makes them sweat.

Being in anguish, He prayed more fervently, and His sweat became like drops of blood falling to the ground.]
