Genesis 5:21
20 The entire lifetime of Jared was 962 years, and then he died. 21 When Enoch had lived 65 years, he became the father of Methuselah. 22 After he became the father of Methuselah, Enoch walked with God for 300 years, and he had other sons and daughters. 23 The entire lifetime of Enoch was 365 years. 24 Enoch walked with God, and then he disappeared because God took him away.
Sirach 44:16
Ben Sira, Ecclesiasticus14 Their bodies are buried in peace, but their name lives on generation after generation. 15 The assembly declares their wisdom, and the congregation proclaims their praise. 16 Enoch pleased the Lord and was taken up, an example of repentance to all generations. 17 Noah was found perfect and righteous; in the time of wrath he kept the race alive; therefore a remnant was left on the earth when the flood came. 18 Everlasting covenants were made with him that all flesh should never again be blotted out by a flood.
Notes and References
"... The passage says that Enoch 'walked with God' after the birth of Methuselah; the clear implication is that before Methuselah's birth he did not walk with God. If so, it would seem that Enoch's great virtue, and the reason for God's taking him, was that he repented. Although he may not have been an exemplary youth, Enoch began to walk with God at age sixty-five and thus became, in the Ben Sira text cited above, ;an example of repentance to all generations.' ..."
