'Sweat' in the Bible

by the sweat of thy face thou dost eat bread till thy return unto the ground, for out of it hast thou been taken, for dust thou art, and unto dust thou turnest back.'

Linen bonnets are on their head, and linen trousers are on their loins, they are not restrained with sweat.

and having been in agony, he was more earnestly praying, and his sweat became, as it were, great drops of blood falling upon the ground.
