GENESIS 5: 21-24
And Enoch lived sixty and five years, and begat Methuselah:
And Enoch walked with God after he begat Methuselah three hundred years, and begat sons and daughters;
And all the days of Enoch were Three hundred sixty and five years;
And Enoch walked with God: and he was not; for God took him.
[Dake A.R. Bible].
[v22: And Enoch walked with God]: Heb. ‘halak’, to walk up and down, be conversant. Cp. Ex. 2:5; 14:29; Lev. 26:30; Josh. 5:6; 1 Sam. 8:3; 12:2.
Enoch and Noah were the only antediluvians ‘who walked with God’ [5:22; 6:9].
Abel, Enoch and Noah are the only ones referred to in the Bible as being godly during this age [4:4, 5:22; 7:1; Lk.17:26-27; 1Pet.3:20; 2Pet.2:4-5; Heb.11:1-7; Jude 14].
This ‘walk’ with God might have been as literal as with Adam [2:19; 3:8].
[v22: And Enoch walked with God After he begat Methuselah 300 years]: Why not before Methuselah was born? Could it be that something happened at this time that would have turned him to God. It is clear that at this time he did receive a revelation from God, for he named his son ‘Methuselah’, which means “when he is dead it [the deluge] shall come.” He also foretold the 2nd Coming of Christ to destroy the ungodly [Jude 14].
[v23: And all the days of Enoch were three hundred sixty and five years]: That is, all his days on earth at that time. Besides living 365 years on earth, he has now lived about 5,310 years in heaven, making around 5,675 years he has lived without death.
He will return as one of the two witnessed of Rev. 11 to complete his earthly life and die [Rev.11:7], as is appointed unto all men [Heb.9:27].
It is said of each of the others in this chapter that “he died” [v5, 8, 11, 14, 17, 20, 27, 31], but not of Enoch “he was not, for God took him” [v24].
[v24: and he was not, for God took him]: That is, translated him without dying as in the case of Elijah [2 Kings 2; Heb.11:5].
His is one of the briefest and most outstanding biographies – one sentence revealing the history of 365 years, 300 of which were believing, humble, holy walking with God.
[v27: And all the days of Methuselah were nine hundred and sixty and nine years: and he died]: The longest earthly life on record.
His father still lives in heaven and will again live on earth and die as one of the two witnesses [Rev.11:3-11].
Enoch, therefore, and not Methuselah is the oldest man that ever lived.
All men would have lived forever if man had not sinned. All will live forever physically in the new earth and carry out God’s original program [Rev. 21-22, notes].
