set on the other side and facing you: a wind coming head-on, a person standing across from you, or someone whose stance is against you.
The picture underneath this word is simple and physical: something is over on the other side, turned toward you. A wind that hits the bow of a boat is this word. So is the soldier standing directly across from the man on the cross. Everything else the word does grows out of that one picture.
The New Testament uses it in three settings, and it helps to see them together:
- a wind blowing straight at a boat so that the crew cannot make headway
- a person positioned directly across from someone else, face to face
- a person or an action deliberately set against someone, in attitude or in deed
Because the picture is about position, hostility is not built in. When the centurion in Mark 15:39 stands facing Jesus, the word says only where he is standing. But a position easily becomes a stance, and when the word describes people rather than weather, it usually means they have taken sides against someone: Paul says he once did many things against the name of Jesus, and he says the persecutors in Thessalonica had set themselves against everyone.
Greek had neighboring words that specialize where this one stays general. There is a stronger term for a settled adversary (ὑπεναντίος), and a closely related form (ἐναντίον) became an everyday way of saying "in front of" or "in the sight of" someone, with the opposition drained out of it. This adjective sits between them, keeping both the plain sense of facing and the sharper sense of being against.
