a wall: the low boundary of stacked stones that rings a vineyard, field, or courtyard and keeps safe whatever is inside it.
Israel's hill country was farmed in terraces, and the stones cleared out of the soil went into low walls running along the edge of every vineyard and field. That is what this word names. It is not a fortification and not the side of a building, but the ordinary boundary of piled stone that says where one plot ends and the next begins, laid up without mortar, low enough to step over and easy enough to knock a gap in.
Because the barrier is that modest, the Bible keeps coming back to the same handful of things it does:
- it marks the edge of a plot and keeps stray animals off the vines
- it pens a traveler into a narrow lane running between two vineyards
- it can be pulled down in an afternoon, leaving everything inside exposed
- it hides snakes in its gaps, so breaking through one is a good way to get bitten
Because that thin line of stone is all that stands between the vines and whatever is outside, the word slides easily into a picture of protection. When Ezra thanks God for giving Israel a wall in Judah and Jerusalem, he is not describing masonry. When Ezekiel looks for someone to build up the wall and stand in the gap, he is looking for a person willing to be the nation's only defense. The same picture also runs in reverse: God can throw a wall across someone's road to shut her in rather than keep her safe.
Three neighboring Hebrew words are easy to confuse with it: the high fortification wall of a walled city (חוֹמָה), the wall of a house or a room (קִיר), and a hedge of thorny growth (מְשׂוּכָה), which Isaiah 5:5 tears away alongside the vineyard's stone wall.
