Matthew Henry commentary on Proverbs 20:8-12
Embedded KJV/source Scripture
10 Divers weights, and divers measures, both of them are alike abomination to the Lord .
See here, 1. The various arts of deceiving that men have, all which evils the love of money is the root of. In paying and receiving money, which was then commonly done by the scale, they had divers weights, an under-weight for what they paid and an over-weight for what they received; in delivering out and taking in goods they had divers measures, a scanty measure to sell by and a large measure to buy by. This was done wrong with plot and contrivance, and under colour of doing right. Under these is included all manner of fraud and deceit in commerce and trade. 2. The displeasure of God against them. Whether they be about the money or the goods, in the buyer or in the seller, they are all alike an abomination to the Lord. He will not prosper the trade that is thus driven, nor bless what is thus got. He hates those that thus break the common faith by which justice is maintained, and will be the avenger of all such.

11 Even a child is known by his doings, whether his work be pure, and whether it be right.
The tree is known by its fruits, a man by his doings, even a young tree by its first fruits, a child by his childish things, whether his work be clean only, appearing good (the word is used ch. xvi. 2 ), or whether it be right, that is, really good. This intimates, 1. That children will discover themselves. One may soon see what their temper is, and which way their inclination leads them, according as their constitution is. Children have not learned the art of dissembling and concealing their bent as grown people have. 2. That parents should observe their children, that they may discover their disposition and genius, and both manage and dispose of them accordingly, drive the nail that will go and draw out that which goes amiss. Wisdom is herein profitable to direct.

12 The hearing ear, and the seeing eye, the Lord hath made even both of them.
Note, 1. God is the God of nature, and all the powers and faculties of nature are derived from him and depend upon him, and therefore are to be employed for him. It was he that formed the eye and planted the ear ( Ps. xciv. 9 ), and the structure of both is admirable; and it is he that preserves to us the use of both; to his providence we owe it that our eyes are seeing eyes and our ears hearing ears. Hearing and seeing are the learning senses, and must particularly own God's goodness in them. 2. God is the God of grace. It is he that gives the ear that hears God's voice, the eye that sees his beauty, for it is he that opens the understanding.

13 Love not sleep, lest thou come to poverty; open thine eyes, and thou shalt be satisfied with bread.
Note, 1. Those that indulge themselves in their ease may expect to want necessaries, which should have been gotten by honest labour. "Therefore, though thou must sleep (nature requires it), yet love not sleep, as those do that hate business. Love not sleep for its own sake, but only as it fits for further work. Love not much sleep, but rather grudge the time that is spent in it, and wish thou couldst live without it, that thou mightest always be employed in some good exercise." We must allow it to our bodies as men allow it to their servants, because they cannot help it and otherwise they shall have no good of them. Those that love sleep are likely to come to poverty, not only because they lose the time they spend in excess of sleep, but because they contract a listless careless disposition, and are still half asleep, never well awake. 2. Those that stir up themselves to their business may expect to have conveniences: " Open thy eyes, awake and shake off sleep, see how far in the day it is, how thy work wants thee, and how busy others are about thee! And, when thou art awake, look up, look to thy advantages, and do not let slip thy opportunities; apply thy mind closely to thy business and be in care about it. It is the easy condition of a great advantage: Open thy eyes and thou shalt be satisfied with bread; if thou dost not grow rich, yet though shalt have enough, and that is as good as a feast."

14 It is naught, it is naught, saith the buyer: but when he is gone his way, then he boasteth.
See here 1. What arts men use to get a good bargain and to buy cheap. They not only cheapen carelessly, as if they had no need, no mind for the commodity, when perhaps they cannot go without it (there may be prudence in that), but they vilify and run down that which yet they know to be of value; they cry, " It is naught, it is naught; it has this and the other fault, or perhaps may have; it is not good of the sort; and it is too dear; we can have better and cheaper elsewhere, or have bought better and cheaper." This is the common way of dealing; and after all, it may be, they know the contrary of what they affirm; but the buyer, who may think he has no other way of being even with the seller, does as extravagantly commend his goods and justify the price he sets on them, and so there is a fault on both sides; whereas the bargain would be made every jot as well if both buyer and seller would be modest and speak as they think. 2. What pride and pleasure men take in a good bargain when they have got it, though therein they contradict themselves, and own they dissembled when they were driving the bargain. When the buyer has beaten down the seller, who was content to lower his price rather than lose a customer (as many poor tradesmen are forced to do—small profit is better than none), then he goes his way, and boasts what excellent goods he has got at his own price, and takes it as an affront and a reflection upon his judgment if any body disparages his bargain. Perhaps he knew the worth of the good better than the seller himself did and knows how to get a great deal by them. See how apt men are to be pleased with their gettings and proud of their tricks; whereas a fraud and a lie are what a man ought to be ashamed of, though he have gained ever so much by them.
