This common word for wall or fence describes various kinds of enclosing barriers: roadside walls (as in Balaam's narrow path), vineyard walls (in Isaiah's parable), city fortifications, and property boundaries. The wall serves protective and delimiting functions, marking what belongs to whom and providing security. Isaiah's prophetic image of removing the vineyard's wall—leaving it vulnerable to wild animals—powerfully communicates God's withdrawal of protection. Proverbs uses the broken-down wall as a figure for the consequences of negligence. The word emphasizes the wall's function as boundary and barrier rather than its construction materials.
