The Bible explicitly states that two prophets, Enoch and Elijah, did not experience death as typically understood.
Enoch
Enoch is mentioned in the Book of Genesis (Genesis 5:24) as having "walked faithfully with God; then he was no more, because God took him away." This is widely interpreted as Enoch being taken directly into God's presence without dying. His story is expanded upon in other religious texts, further solidifying the belief that he was translated to Heaven.
Elijah
The prophet Elijah is described in the Second Book of Kings (2 Kings 2:11) as ascending into heaven in a whirlwind: "As they were walking along and talking together, suddenly a chariot of fire appeared with horses of fire and separated the two of them, and Elijah went up to heaven in a whirlwind." This dramatic account is the basis for the belief that Elijah never died but was taken alive to God.
Therefore, according to scripture, Enoch and Elijah are the two individuals specifically identified as not having experienced death.
