Enoch and Elijah died
Enoch Died:
The lifetime of Enoch totaled three hundred sixty and five years. (Gen 5:23).
Heb 11:4-5 By faith Abel offered unto YHVH a more excellent offering than Cain, by which he had this testimony against Cain, that he was righteous and Cain was not righteous (1Joh 3:12), YHVH testifying of his gifts; and by his testimony, he being killed yet speaks. Faithful Enoch was relocated (compare Act 8:39-40) that he should not be killed, like Abel, and was not found by those who were violent, like Cain (Jude 14-15 & Gen 6:11), because YHVH had relocated him; for before his conveyance he had this testimony against his detractors, that he pleased YHVH.
Heb 11:13 These all died (including Enoch) trusting, not having received the Promise (Gen 15:5-6; 17:4; 26:4-5; 28:3,14), but having seen it afar off, and were persuaded of the promise, and embraced the promise, and confessed that they were strangers and pilgrims elsewhere on the earth.
Elijah Died:
Elijah was another prophet who was conveyed to an undisclosed location (presumably to allow Elisha to have center stage, 1Kin 19:16).
2Kin 2:11 And it came to pass, as Elijah and Elisha still went on, and talked, that, behold, there appeared a chariot of fire, and horses of fire, and parted them both asunder; and Elijah went up by a whirlwind into the sky.
The disciples of the prophets knew that Elijah had only been moved to another location and were anxious for his well-being.
2Kin 2:16-17 And the prophets' disciples said unto Elisha, "Behold now, there be with thy servants fifty strong men; let them go, we pray thee, and seek thy master Elijah: lest peradventure the Spirit of YHVH hath taken him up, and cast him upon some mountain, or into some valley". And he said, "Ye shall not send". And when they urged him till he was ashamed, he said, "Send". They sent therefore fifty men; and they sought three days, but found him not.
Elijah had not gone too far because years later (2Kin 3:1 & 2Kin 8:16), we find him corresponding with King Jehoram.
2Chr 21:12 And there came a writing to Jehoram from Elijah the prophet, saying, Thus saith YHVH Elohim of David thy father, Because thou hast not walked in the ways of Jehoshaphat thy father, nor in the ways of Asa king of Judah.
Both Elijah and Enoch are dead, awaiting the Resurrection.
