The recurrence of the Hebrew word massa', translated "oracle"or "burden,"prescribes the boundaries of this section of text.140These chapters present the nations over which Immanuel is ruler, and they expand the idea of God's hatred of Assyria's pride (10:5-34; cf. 2:6-22; 13:11, 19; 14:11; 16:6; 17:7-11; 23:9). They are announcements of doom on these nations, but they are also announcements of salvation for Israel if she would trust in Yahweh. Isaiah delivered them to Israel rather than to the nations mentioned. Thus they assured the Israelites of Yahweh's sovereignty over the nations with a view to encouraging God's people to trust in the Lord (cf. Jer. 46-51; Ezek. 25-32; Amos 1-2). It would be foolish to trust in nations whom God has doomed. The unifying theme is the pride of these nations. Exalting self and failing to acknowledge God results in destruction.
". . . He [God] will hold every nation accountable for its actions."141
It is helpful to notice the structure of this section and the one that follows it.142
Note that each of the first two columns of oracles (chs. 13-23) begins with Babylon, and the third deals with Israel, which the peoples of the world surround. In the first list Babylon is to Israel's north, Philistia to the west, Moab to the east, and Egypt to the south. In the second list Babylon is to the north, Edom to the south, Arabia to the east, and Tyre to the west. Thus the selection of these nations suggests that Israel occupies the central place in God's plans, and the surrounding nations are vulnerable.143
