“The great God that formed all things both rewardeth the fool, and rewardeth transgressors.”
“Like an archer who wounds everyone is one who hires a passing fool or drunkard.” – ESV
This proverb is a challenging one because of how many different ways it could be translated. As a matter of fact, practically every scholarly commentary admits the Hebrew in this proverb is difficult to interpret. That is why I am going to quote several of them before I leave my final thought for you.
Spence-Jones (The Pulpit Commentary)
Few passages have given greater difficulty than this verse; almost every word has been differently explained. The Authorized Version is, The great God that formed all things both rewardeth the fool, and rewardeth transgressors; Revised Version, As an archer (Job 16:13) that woundeth all, so is he that hireth the fool and he that hireth them that pass by. At first sight one would hardly suppose that these could be versions of the same passage. 
Garrett (The New American Commentary)
The Hebrew of v. 10 is almost unintelligible and thus subject to numerous interpretations, all of which are hypothetical. As the NIV has it, the verse reaffirms that one should not commit important tasks to fools (as in v. 6). Notwithstanding all the difficulties of the text, that does seem to be the main point.
Friedrich and Delitzsch (Commentary on the Old Testament)
All that we have hitherto read is surpassed in obscurity by this proverb, which is here connected because of the resemblance of ושכר to שכור. We translate it thus, vocalizing differently only one word:
Much bringeth forth from itself all; But the reward and the hirer of the fool pass away.
Our translation [KJV] gives this verse a different reading in the text and in the margin; and accordingly it expresses either, 1. The equity of a good God. The Master, or Lord (so Rab signifies), or, as we read it, The great God that formed all things at first, and still governs them in infinite wisdom, renders to every man according to his work. … Or, 2. The iniquity of a bad prince (so the margin reads it): A great man grieves all, and he hires the fool; he hires also the transgressors. When a wicked man gets power in his hand, by himself, and by the fools and knaves whom he employs under him, whom he hires and chooses to make use of, he grieves all who are under him and is vexatious to them. We should therefore pray for kings and all in authority, that, under them, our lives may be quiet and peaceable.
Anthony Baker (Proverbial Thought)
So, here is what I think. Feel free to quote me 200 years from now.
A man is a fool when he employs a fool to complete a task. However, the biggest fool is one who thinks God, the Almighty Archer, will miss the target when He holds the wicked accountable.
We are always under His watchful eye, but the fool is never out of His “sights.”
