The oracles appear to be very deliberately arranged in a manner that accords with the points of the compass. For example:
Against Damascus (northeast), Amos 1:3–5
Against Gaza (southwest), Amos 1:6–8
Against Tyre (northwest), Amos 1:9–10
Against Edom, Ammon, and Moab (southeast), Amos 1:11 – 2:3
Against Judah (south), Amos 2:4–5
Against Israel (north), Amos 2:6–16
3 Thus says the LORD: “For three transgressions of Damascus, and for four, I will not revoke the punishment, because they have threshed Gilead with threshing sledges of iron.
