'Net' in the Bible

He taketh up all of them with the hook, he catcheth them in his net, and gathereth them into his drag; therefore he rejoiceth and is glad:

therefore he sacrificeth unto his net, and burneth incense unto his drag; for by them his portion is become fat, and his meat dainty.

Shall he therefore empty his net, and not spare to slay the nations continually?
