Albert Barnes Commentary Job 19:16

"I call unto my servant, and he giveth me no answer, [Though] I entreat him with my mouth." — Job 19:16 (ASV)

I called my servant — He lost all respect for me, and paid me no attention.

I entreated him — I ceased to expect “obedience,” and tried to see what “persuasion” would do. I ceased to be master in my own house.
