Skin of my teeth (Hebrew: ע֣וֹר שִׁנָּֽי‎‎ ‘ō-wr šin-nāy) is a phrase from the Bible. In Job 19:20, the King James Version of the Bible says, "My bone cleaveth to my skin and to my flesh, and I am escaped with the skin of my teeth." In the Geneva Bible, the phrase is rendered as "I haue escaped with the skinne of my tethe."

In modern times, "by the skin of my teeth" is used to describe a situation from which one barely managed to escape. - Wikipedia
