"Therefore shall a strong people glorify thee; a city of terrible nations shall fear thee." — Isaiah 25:3 (ASV)

The words paint the effect of the downfall of the imperial oppressor on the outlying fiercer nations, who were thus taught to recognize the righteous judgments of the God of Israel. (Revelation 15:4.)
