Albert Barnes Commentary Job 5:14

"They meet with darkness in the day-time, And grope at noonday as in the night." — Job 5:14 (ASV)

They meet with darkness in the daytime - Margin, “run into;” compare the notes at (Isaiah 59:10). The sense is that where there is really no obstacle to the accomplishment of an honest plan—no more of an obstacle than for a person to walk in the daytime—they become perplexed and embarrassed, much as a person would be if sudden darkness were to envelop them at midday.

The same sentiment occurs in (Job 12:25). A life of honesty and uprightness will be attended with prosperity, but a person who attempts to carry out their plans by trickery and artifice will meet with unexpected embarrassments.

The sentiment in all these expressions is that God embarrasses the cunning, the crafty, and the artful, but gives success to those who are upright; and that, therefore, He is worthy of confidence.
