Albert Barnes Commentary Job 8:20

"Behold, God will not cast away a perfect man, Neither will he uphold the evil-doers." — Job 8:20 (ASV)

Behold, God will not cast away a perfect man - On the meaning of the word perfect, see the note at Job 1:1. The sentiment of Bildad, or the inference which he draws from the whole argument, is that God will be the friend of the pious, but that He will not aid the wicked. This accords with the general sentiment maintained in the argument of the friends of Job.

Neither will he help the evil doers - Margin, “Take the ungodly by the hand.” This is in accordance with the Hebrew. The figure is that of taking one by the hand in order to assist him; see Isaiah 42:6.
