Charles Ellicott Commentary Job 4:3

"Behold, thou hast instructed many, And thou hast strengthened the weak hands." — Job 4:3 (ASV)

Behold, you have instructed many.—There is a conspicuous lack of feeling in Eliphaz. Without any true sympathy, however, he may have given the outward signs of it (Job 2:12–13).

He charges Job with an inability to derive from his own principles the support which he had expected them to afford to others, and seems almost to rejoice malevolently that one who had been so great a help to others was now in need of help himself. Calamity touches you, and you are overwhelmed by it.
