'Sweat' in the Bible

By the sweat of your faceYou will eat bread,Till you return to the ground,Because from it you were taken;For you are dust,And to dust you shall return.”

Linen turbans shall be on their heads and linen undergarments shall be on their loins; they shall not gird themselves with anything which makes them sweat.

And being in agony He was praying very fervently; and His sweat became like drops of blood, falling down upon the ground.
