Well somewhat of a trick question. The oldest man in the Bible was Methuselah. He lived to be 969 years old. His father was Enoch. The bible tells us very little about both of these men, but what it does is very interesting.
When Enoch had lived 65 years, he fathered Methuselah. Enoch walked with God after he fathered Methuselah 300 years and had other sons and daughters. Thus all the days of Enoch were 365 years. Enoch walked with God, and he was not, for God took him. When Methuselah had lived 187 years, he fathered Lamech. Methuselah lived after he fathered Lamech 782 years and had other sons and daughters. Thus all the days of Methuselah were 969 years, and he died.
It is a trick question,
because it presupposes that Enoch died. What we learn from this text is that he didn’t die but was taken by God. Enoch walked with God, and he was not, for God took him. He was in a sense raptured. Though this is not the only place in the bible were it talks about Enoch. Hebrews 11:5 talks about him being taken by God and In Jude 1:14-15 there is a prophesy that was given by Enoch. So what we know about Enoch was that he pleased God, walked with him, was a prophet and didn’t experience death. With this in mind lets look at what he named his son, Methuselah. What the word “methuselah” literally means is “his death shall bring”, or “when he dies it will come.” So what happened when Methuselah died. I have a time line that uses the detailed ages given by Genesis that makes this a lot easier to see.
What happens when he dies? The flood, the same exact year of his death marks the destruction of the earth. Also notice who Methuselah more than likely knew. He was alive more than 200 years before Adam died. God’s word truly is amazing.
