Exodus (bible OT) contains a phrase (in the voice of god) that is remarkably precocious of its purpose: asserting, through unconventional grammar, a certain essentially existentialist claim completely unique to its speaker.

έγώ είμι ό ών ( pardon the abuse of the acute accent, I can't get this IME to reproduce the grave) which is translated as "I am that I am," means something dynamically close to "I am the IS." or "I am that which IS." A structure that implies being outside the passage of time, uncreated and therefore not dependent on reproduction to continue surviving, or even on life to keep on living.
