Charles Ellicott Commentary Habakkuk 2:1

"I will stand upon my watch, and set me upon the tower, and will look forth to see what he will speak with me, and what I shall answer concerning my complaint." — Habakkuk 2:1 (ASV)

The Tower. —The practice of ascending a high place to secure an extensive view suggests the figure here. (See 2 Kings 9:17; 2 Samuel 18:24.) In a yet bolder metaphor Isaiah represents himself as appointing a watchman, who brings reports from his tower. We need not suppose that Habakkuk literally went to a solitary height to wait for a revelation. Balaam, the heathen soothsayer, did so (Numbers 23:3), but his conduct throws no light on the customs of the Jewish prophets.

What he will say to me. —Better, what He will say in me, and what answer I will make to my complaint: i.e., of what solution to the perplexities I am deploring, Jehovah will make me the mouthpiece.
