John Gill Commentary Job 27:9

"Will God hear his cry, When trouble cometh upon him?" — Job 27:9 (ASV)

Will God hear his cry when trouble comes upon him ? No, he hears not sinners, and such as regard iniquity in their hearts (Psalms 66:18); every man has trouble more or less in this life, even the best of men; and generally speaking they have the most, and wicked men the least; but when death comes, he is a king of terrors to them, and they find sorrow and trouble; and especially at the day of judgment, when they will cry for mercy; and hypocrites, as the foolish virgins, will cry, "Lord, Lord, open unto us" (Matthew 25:11); but when they call for mercy, the Lord will not answer, but laugh at their calamity, and mock when their fear comes (Proverbs 1:26Proverbs 1:28);

but God hears the cries of his people when in trouble, whether in life or in death, and is a present help unto them; and when strength and heart fail, he is their portion, and will be so forevermore; and though sometimes they think he does not hear them, as Job sometimes complains, yet he makes it appear that he does sooner or later, and so Job describes himself as one that "calls upon God, and he answers him" (Job 12:4); and therefore might conclude he was no hypocrite.
