Habakkuk 1:15 - Matthew Poole's English Annotations on the Holy Bible

They; either more generally oppressors every where, or else particularly the Chaldeans. Take up; draw them out slily and craftily, when they are taken by his bait. All of them without distinction, all alike, good or bad. With the angle: it may refer to the delight these oppressors took in these courses, or to the more private way of destroying. They catch them in their net; another method of the Chaldean rapine, like catching of fish, not singly and one by one, but destroying many together. And gather them; as if they could never have enough, these Chaldeans do, fisher-like, drive men into their nets and snares. In their drag: this is a third way of destroying fish. The Chaldeans would use all ways to devour the Jews. Therefore they, the greedy and cruel Chaldeans, rejoice, both in their own gain and in the Jews ruin. And are glad: it is doubled to show the certainty of the thing, and probably to intimate the double joy they took in their prosperous oppression.
