Cherubim

He drove out the man, and at the east of the garden of Eden he placed the [t]cherubim and a flaming sword that turned every way to guard the way to the tree of life.

Gen. 3:22–24 The couple is expelled from the garden. God begins a sentence in v. 22 and breaks off without finishing it—for the man to live forever (in his sinful condition) is an unbearable thought, and God must waste no time in preventing it (“therefore the Lord God sent him out from the garden”). The tree of life, then, probably served in some way to confirm a person in his or her moral condition (cf. Prov. 3:18; 11:30; 13:12; Rev. 2:7; 22:2, 14, 19). According to Gen. 2:15, the man was put in the garden to work it and keep or guard it. Outside the garden the man will have to work the ground, but the task of keeping or guarding the garden is given to the cherubim (3:24). By allowing themselves to be manipulated by the serpent, the couple failed to fulfill their priestly duty of guarding the garden. Consequently, their priestly status is removed from them as they are put out of the sanctuary. The placing of cherubim to the east of the garden is reflected in the tabernacle and temple, where cherubim were an important component in the structure and furnishings (see The Ark of the Covenant).
