dwell

Nebuchadnezzar, first of the Gentile world-kings in whom the times of the Gentiles (Luk 21:24); (Rev 16:14) began, perfectly comprehended the universality of the sway committed to him (Dan 2:37); (Dan 2:38) as also did Cyrus (Ezr 1:2). That they did not actually subject the known earth to their sway is true, but they might have done so. The earth lay in their power.

I blessed the most High

A progress may be traced in Nebuchadnezzar's apprehension of the true God.

(1) "God" is "a God of gods" [one amongst the national or tribal gods, but greater than they], and a "Lord Adonai", signifies "Master of kings", and a "revealer of secrets" (Dan 2:47).

(2) He is still a Hebrew deity, but Master of angels, and a God who responds to faith (Dan 3:28).

(3) Here (Dan 4:34); (Dan 4:35) the king rises into a true apprehension of God.

Compare Darius, (Dan 6:25-27).
