Charles Ellicott Commentary Job 19:6

"Know now that God hath subverted me [in my cause], And hath compassed me with his net." — Job 19:6 (ASV)

Know now that God hath overthrown me. —Bildad had spoken a great deal about the wicked being snared by his own sin, and now Job, without actually quoting his words—for he uses a word for net that Bildad had not used—speaks to their substance. It is God who has taken him in His net and encompassed him with it. This is the assertion he has made before (Job 16:7; Job 13:27, and elsewhere).
