What does Isaiah 26:13 mean?
Isaiah declared with great confidence that God will establish peace for Israel once more (Isaiah 26:12). Isaiah knows God has been the power behind everything Israel has ever accomplished (Psalm 44:1–3). God has won every victory over their enemies (Isaiah 26:12).Now Isaiah admits that other lords, besides the one true Lord God of Israel, have ruled over them. It's unclear if he is referring to the leaders of foreign nations who have conquered Israel in the past. Or he may be referring to false gods to which the people of Israel and Judah have willingly submitted.
Whatever is meant by the "other lords" who have ruled over Israel in the past, Isaiah makes it clear they are now mere fragments of history. Israel honors only the Lord. Only God is worthy of praise and worship.
