The Four Places That Belong to the Lord ( Jubilees 4.26)
This article argues that the original name for the mountain on which Enoch made his offering in Eden was the mountain of incense (Jub. 4.25) and that it and the first mountain in 4.26 (the mountain of Eden/Paradise) are the same mountain. The second mountain in 4.26, the mountain of the east, is Mt Lubar where the ark landed at the end of the flood and where Noah lived until his death. All four mountains in 4.26 are places where God had or would specially reveal himself to chosen individuals and for that reason were holy to the Lord.
