Alienate
[ 1,,G526, apallotrioo ]consists of apo, from," and the above; it signifies "to be rendered an alien, to be alienated." In Ephesians 2:12 the RV corrects to the verbal from "alienated," for the noun "aliens;" elsewhere in Ephesians 4:18; Colossians 1:21; the condition of the unbeliever is presented in a threefold state of "alienation,"
(a) from the commonwealth of Israel,
(b) from the life of God,
(c) from God Himself. The word is used of Israelites in the Sept. of Ezekiel 14:5 ("estranged") and of the wicked in general, Psalms 58:3.
