Habakkuk 2:1
And having unburdened his heart and pleaded with the Lord, he waits for the answer. His heart is with his people, and he must watch for the end of the Lord. He is no hireling; he cares for the flock, and cannot flee. His service for Israel had not been lightly taken up, and it cannot therefore be quickly laid down. He must see the end of it; and for this, he sets himself upon the watch-tower.
