Elihu says, "Surely God will not hear an empty cry" (35:13). Doesn't God hear those who cry to him?

These are Elihu's words, and he says them after a picture of his own: people "cry out" under oppression (35:9), but no one says, "Where is God my Maker, who gives songs in the night" (35:10), and "There they cry, but no one answers, because of the pride of evil men" (35:12). He doesn't say which cries are empty beyond these verses. Other Scripture says God hears. "I have surely seen the affliction of my people who are in Egypt, and have heard their cry" (Exodus 3:7). "If you take advantage of them at all, and they cry at all to me, I will surely hear their cry" (Exodus 22:23), where cry at all is the verb of 35:12's cry (tap cry). "The righteous cry, and the LORD hears" (Psalm 34:17). Other Scripture also speaks of cries not heard. "If I cherished sin in my heart, the Lord wouldn’t have listened" (Psalm 66:18). "Then they will cry to the LORD, but he will not answer them" (Micah 3:4). "Whoever stops his ears at the cry of the poor, he will also cry out, but shall not be heard" (Proverbs 21:13). These verses stand side by side in Scripture. Elihu turns his words to Job in 35:14-16. These notes don't say which of these verses fits the cries of 35:9-12, or whether any cry of Job's was empty.
