Adam Clarke on Job 24:15

The eye also of the adulterer - This is another sin particularly of the city. The adulterer has made his assignation; he has marked the house of her into whose good graces he has insinuated himself, called digging through the house; he waits impatiently for the dusk; and then goes forth, having muffled or disguised his face, and spends a criminal night with the faithless wife of another man. The morning dawns: but it is to him as the shadow of death, lest he should be detected before he can reach his own home. And if one know him - if he happen to be recognized in coming out of the forbidden house; the terrors of death seize upon him, being afraid that the thing shall be brought to light, or that he shall be called to account, a sanguinary account, by the injured husband. This seems to be the general sense of the very natural picture which Job draws in the Job 24:15, Job 24:16, and Job 24:17.
