Enoch
The second mention is in the Epistle to the Hebrews which says, "By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God." (Hebrews 11:5 KJV). This means that he did not experience the mortal death which  Adam's other descendants experienced, which makes sense with Genesis 5:24 KJV, as it says, "And Enoch walked with God: and he [was] not; for God took him."
