Matthew Henry commentary on Proverbs 25:16-20
Embedded KJV/source Scripture
18 A man that beareth false witness against his neighbour is a maul, and a sword, and a sharp arrow.
Here, 1. The sin condemned is bearing false witness against our neighbour, either in judgment or in common conversation, contrary to the law of the ninth commandment. 2. That which it is here condemned for is the mischievousness of it; it is in its power to ruin not only men's reputation, but their lives, estates, families, all that is dear to them. A false testimony is every thing that is dangerous; it is a maul (or club to knock a man's brains out with), a flail, which there is no fence against; it is a sword to wound near at hand and a sharp arrow to wound at a distance; we have therefore need to pray, Deliver my soul, O Lord! from lying lips, Ps. cxx. 2 .

19 Confidence in an unfaithful man in time of trouble is like a broken tooth, and a foot out of joint.
1. The confidence of an unfaithful man (so some read it) will be like a broken tooth; his policy, his power, his interest, all that which he trusted in to support him in his wickedness, will fail him in time of trouble, Ps. lii. 7 . 2. Confidence in an unfaithful man (so we read it), in a man whom we thought trusty and therefore depended on, but who proves otherwise; it proves not only unserviceable, but painful and vexatious, like a broken tooth, or a foot out of joint, which, when we put any stress upon it, not only fails us, but makes us feel from it, especially in time of trouble, when we most expect help from it; it is like a broken reed, Isa. xxxvi. 6 . Confidence in a faithful God, in time of trouble, will not prove thus; on him we may rest and in him dwell at ease.

20 As he that taketh away a garment in cold weather, and as vinegar upon nitre, so is he that singeth songs to an heavy heart.
1. The absurdity here censured is singing songs to a heavy heart. Those that are in great sorrow are to be comforted by sympathizing with them, condoling with them, and concurring in their lamentation. If we take that method, the moving of our lips may assuage their grief ( Job xvi. 5 ); but we take a wrong course with them if we think to relieve them by being merry with them, and endeavouring to make them merry; for it adds to their grief to see their friends so little concerned for them; it puts them upon ripping up the causes of their grief, and aggravating them, and makes them harden themselves in sorrow against the assaults of mirth. 2. The absurdities this is compared to are, taking away a garment from a man in cold weather, which makes him colder, and pouring vinegar upon nitre, which, like water upon lime, puts it into a ferment; so improper, so incongruous, is it to sing pleasant songs to one that is of a sorrowful spirit. Some read it in a contrary sense: As he that puts on a garment in cold weather warms the body, or as vinegar upon nitre dissolves it, so he that sings songs of comfort to a person in sorrow refreshes him and dispels his grief.
Forgiveness of Enemies.
Embedded KJV/source Scripture
21 If thine enemy be hungry, give him bread to eat; and if he be thirsty, give him water to drink: 22 For thou shalt heap coals of fire upon his head, and the Lord shall reward thee.
By this it appears that, however the scribes and Pharisees had corrupted the law, not only the commandment of loving our brethren, but even that of loving our enemies, was not only a new, but also an old commandment, an Old-Testament commandment, though our Saviour has given it to us with the new enforcement of his own great example in loving us when we were enemies. Observe, 1. How we must express our love to our enemies by the real offices of kindness, even those that are expensive to ourselves and most acceptable to them: "If they be hungry and thirsty, instead of pleasing thyself with their distress and contriving how to cut off supplies from them, relieve them, as Elisha did the Syrians that came to apprehend him," 2 King vi. 22 . 2. What encouragement we have to do so. (1.) It will be a likely means to win upon them, and bring them over to be reconciled to us; we shall mollify them as the refiner melts the metal in the crucible, not only by putting it over the fire, but by heaping coals of fire upon it. The way to turn an enemy into a friend is, to act towards him in a friendly manner. If it do not gain him, it will aggravate his sin and punishment, and heap the burning coals of God's wrath upon his head, as rejoicing in his calamity may be an occasion of God's turning his wrath from him, ch. xxiv. 17 . (2.) However, we shall be no losers by our self-denial: "Whether he relent towards thee or no, the Lord shall reward thee; he shall forgive thee who thus showest thyself to be of a forgiving spirit. He shall provide for thee when thou art in distress (though thou hast been evil and ungrateful), as thou dost for thy enemy; at least it shall be recompensed in the resurrection of the just, when kindnesses done to our enemies shall be remembered as well as those shown to God's friends."
