'Net' in the Bible

Each of them with a hook he hath brought up, He doth catch it in his net, and gathereth it in his drag, Therefore he doth joy and rejoice.

Therefore he doth sacrifice to his net, And doth make perfume to his drag, For by them is his portion fertile, and his food fat.

Doth he therefore empty his net, And continually to slay nations spare not?
