Genesis 2:8
7 The Lord God formed the man from the soil of the ground and breathed into his nostrils the breath of life, and the man became a living being. 8 The Lord God planted an orchard in the east, in Eden; and there he placed the man he had formed. 9 The Lord God made all kinds of trees grow from the soil, every tree that was pleasing to look at and good for food. (Now the tree of life and the tree of the knowledge of good and evil were in the middle of the orchard.)
Jubilees 8:19
18 And Noah rejoiced that this portion came forth for Shem and for his sons, and he remembered all that he had spoken with his mouth in prophecy; for he had said: 'Blessed be the Lord God of Shem And may the Lord dwell in the dwelling of Shem.' 19 And he knew that the Garden of Eden is the holy of holies, and the dwelling of the Lord, and Mount Sinai the centre of the desert, and Mount Zion -the centre of the navel of the earth: these three were created as holy places facing each other. 20 And he blessed the God of gods, who had put the word of the Lord into his mouth, and the Lord for evermore.
Notes and References
"... As the Nile is the western limit of Shem’s territory, the boundary now turns to the east. The geographical point named in the east is the Garden of Eden. Genesis 2:8 situates it there: “And the Lord God planted a garden in Eden, in the east,” and naming the Tigris and Euphrates as two of the rivers flowing from it suggests as much. The writer says nothing further about the location of the garden other than to note that one must venture even farther to the east to return to the Rafa Mountains and the mouth of the Tina River from which the sketch of Shem’s borders began. He also reproduces the distinction made in Genesis between the garden and the land of Eden (Genesis 2:8, 10; see Jubilees 3:9, 12) and includes the latter as well in Shem’s lot ... “He knew that the Garden of Eden is the holy of holies.” The author made clear in 3:8-14 that the garden was a sanctuary, since the times at which the first man and woman entered the garden were the bases of some sort of relationship with one another ..."
