east, or what lies in front: the direction of the sunrise, the eastern side of a place, and the lands and peoples that way
Hebrew fixes direction from the body of a person facing the sunrise. East is therefore what is in front, west is behind (אָחוֹר), the right hand is south and the left is north. That is why this one word can mark the eastern side of the tabernacle, a boundary line running eastward, a camp pitched on the east, and simply the space ahead of someone.
From the bare direction the word stretches to name a whole region: the lands and peoples beyond Israel's eastern edge, the home of Abraham's relatives and of the desert raiders who pressed in on the farmland. Job is called the greatest of the people of the east, which sets his story in that world of herds, tents and open country.
The eastward movement carries weight in Genesis. The man and woman are put out east of Eden, Cain settles east, and the builders of Babel travel east to the plain of Shinar, a steady drift away from God's presence. Ezekiel then makes the same direction the road home: the glory of God leaves the temple by the east gate and returns by it.
Nuances
Whether מִקֶּדֶם in Genesis 2:8 locates the garden spatially ("in the east") or temporally ("from the beginning, of old").
- majoritySpatial: God planted the garden "in the east." The narrative sequence and the matching eastward movements at Genesis 3:24; 4:16; 11:2 favor a direction here.; Septuagint, Genesis 2:8 (ἐν Εδεμ κατὰ ἀνατολάς); Gordon J. Wenham, Genesis 1-15, Word Biblical Commentary 1
- minorityTemporal: the phrase means "from the beginning" or "of old," so the garden is primeval rather than eastern.; Aquila (ἀπὸ ἀρχῆθεν) and Theodotion (ἐν πρώτοις), ad Genesis 2:8; Targum Onqelos, Genesis 2:8 (מלקדמין); Augustine, De Genesi ad litteram
