John Gill Commentary Job 34:28

"So that they caused the cry of the poor to come unto him, And he heard the cry of the afflicted." — Job 34:28 (ASV)

So that they cause the cry of the poor to come to him
To God; through their oppressions of the poor they are made to cry by reason of them, and who come to God with their cries, and tears, and supplications, and which enter into the ears of the Lord of hosts;

and he heareth the cry of the afflicted ;
as he did the cry of the Israelites under Egyptian bondage; he is a God hearing and answering prayer, and he particularly attends to the cry of the humble and of the afflicted, and arises for their help and deliverance.
