in front of: in someone's open view, whether facing them, in their plain sight, or standing over against them
At its core this word places one thing in front of another, out in the open and within view. It is not a neutral location word like "near" or "with"; it pictures a face turned toward something, a thing set squarely before the eyes. From that one picture the Bible draws several shades of meaning, and the shade is decided by what is doing the facing and why.
When it describes plain physical position, it means "opposite" or "facing": an army drawn up against another, people camped in front of a mountain, builders working on the stretch of wall directly across from a landmark. When the thing in front is a watching crowd, it shifts to "in full sight of," the language of public exposure: a deed done openly before witnesses, with nothing hidden. When what is set in front is held there by a person's own attention, it becomes mental rather than physical: a sin or a sorrow that stays "ever before me," or God deliberately kept in view as the fixed point of one's life. With words of motion it can mean simply "straight ahead." And when two parties face off, it can carry the edge of opposition, "over against, against."
A common stretched form (joined to small words meaning "from" or "to") adds the idea of distance: standing "off in front," watching from a way off, or keeping aloof. The picture is the same open line of sight, only now stretched out across a gap. English has no single preposition that covers all of this, which is why translators reach for "before," "opposite," "in the sight of," "against," and "in front of" depending on the verse.
