Job 16:10
They have gaped upon me with their mouth; they have smitten me upon the cheek reproachfully; they have gathered themselves together against me. They have gaped upon me with their mouth; they have smitten me upon the cheek reproachfully; they have gathered themselves together against me.
The verse stands in Job's reply to Eliphaz, in which he protests his innocence and longs for death. It belongs to the account of his suffering and of his arguments with his friends about its cause, presenting him as a real, upright man undergoing a trial. Though he was upright, his affliction included people gaping upon him with the mouth in contempt and hostility, smiting him upon the cheek reproachfully, and gathering themselves together against him.
God's children may have to bear reproach and shame, as that smiting of the upright sufferer on the cheek shows. The gaping describes enemies opening the mouth against him in hostility. In this it illustrates how the wicked may open their mouths against the righteous in envy and rage.
