(20) As vinegar upon nitre, by which the nitre is rendered useless.

Is he that singeth songs to an heavy heart.--Not the true sympathy advised by St. Paul. (Romans 12:15.)

Verse 20. - As he that taketh away a garment in cold weather. The proverb gives three instances of what is wrong, incongruous, or unwise, the first two leading up to the third, which is the pith of the maxim. But them is some doubt about the rendering of the first clause. The Authorized Version has the authority of the Syriac, Aquila, and others, and gives an appropriate sense, the unreasonable proceeding being the laying aside of some of one's own clothes in cold weather. But the verb here used, עָדָח (adah), may also mean "to adorn," e.g., with fine garments; hence some expositors understand the incongruity to be the dressing one's self in gay apparel in winter. But, as Delitzsch remarks, there is no reason why fine clothes should not be warm; and if they are so, there is nothing unreasonable in wearing them. The rendering of our version is probably correct. St. Jerome annexes this line to the preceding verse, as if it confirmed the previous instances of misplaced confidence, Et amittit pallium in die frigoris. "Such a one loses his cloak in a day of frost." Vinegar upon nitre. Our nitre, or saltpetre, is nitrate of potash, which is not the substance intended by נֶתֶר (nether). The substance signified by this term is a natural alkali, known to the ancients as natron, and composed of carbonate of soda with some other admixture. It was used extensively for washing purposes, and in cookery and bread making. It effervesces with an acid, such as vinegar, and changes its character, becoming a salt, and being rendered useless for all the purposes to which it was applied in its alkaline condition. So he who pours vinegar on natron does a foolish thing, for he spoils a highly useful article, and produces one which is of no service to him. Septuagint, "As vinegar is inexpedient for a wound (ἕλκει), so suffering falling on the body pains the heart." Schulteus, Ewald, and others, by referring nether to an Arabic source, obtain the meaning "wound," or "sore," titus: "As vinegar on a sore." This gives a most appropriate sense, and might well be adopted if it had sufficient authority. But this is doubtful. Cornelius a Lapide translates the Septuagint rendering, Ὥσπερ ὅξος ἑλκει ἀούμφορον, "Sicut acetum trahit inutile;" and explains that vinegar draws from the soil the nitre which is prejudicial to vegetation, and thus renders ground fertile - a fact in agricultural chemistry not generally known, though Columella vouches for it. A somewhat similar fact, however, is of common experience. Land occasionally becomes what farmers term "sour," and is thus sterile; if it is then dressed with salt. its fertillity is restored. So is he that singeth songs to an heavy heart. The inconsistency lies in thinking to cheer a sorrowful heart by singing merry songs. "A tale out of season," says Siracides, "is as music in mourning" (Ecclus. 22:6). The Greeks denoted cruel incongruity by the proverb, Ἐν, πενθοῦσι παίζειν; "Ludere inter maerentes." As the old hymn says -

"Strains of gladness
Suit not souls with anguish torn." The true Christian sympathy teaches to "rejoice with them that rejoice, to weep with them that weep" (Romans 12:15). Plumptre, in the 'Speaker's Commentary,' suggests that the effervescence caused by the mixture of acid and alkali is taken as a type of the irritation produced by the inopportune songs. But this is importing a modern view into a paragraph, such as would never have occurred to the writer. The Septuagint, followed partially by Jerome, the Syriac, and the Targum, introduces another proverb not found in the Hebrew, "As a moth in a garment, and a worm in wood, so the sorrow of a man hurts his heart."

25:19. Confidence in an unfaithful man is painful and vexatious; when we put any stress on him, he not only fails, but makes us feel for it. 20. We take a wrong course if we think to relieve those in sorrow by endeavouring to make them merry. 21,22. The precept to love even our enemies is an Old Testament commandment. Our Saviour has shown his own great example in loving us when we were enemies. 23. Slanders would not be so readily spoken, if they were not readily heard. Sin, if it receives any check, becomes cowardly. 24. It is better to be alone, than to be joined to one who is a hinderance to the comfort of life. 25. Heaven is a country afar off; how refreshing is good news from thence, in the everlasting gospel, which signifies glad tidings, and in the witness of the Spirit with our spirits that we are God's children! 26. When the righteous are led into sin, it is as hurtful as if the public fountains were poisoned. 27. We must be, through grace, dead to the pleasures of sense, and also to the praises of men. 28. The man who has no command over his anger, is easily robbed of peace. Let us give up ourselves to the Lord, and pray him to put his Spirit within us, and cause us to walk in his statutes.As he that taketh away a garment in cold weather,.... Either takes it off of himself, or another person, when it would be rather more proper to put another garment on, and so is exposed to the injury of cold weather;

and as vinegar upon nitre: nitre was found in Egypt, beyond Memphis, as Strabo says (p); there were two mines of nitre, which produced much, and thence it was called the Nitriotic Nome: others say, nitre has its name from Nitria, a town in Egypt (q), which gives name to the Nitrian desert, where there is a lake called Latron; from the bottom of which, that sort of nitre, called Natron, arises to the top, as is apprehended, and there, by the heat of the sun, condenses into this kind of substance (r), which will react with an acid; and so vinegar poured upon it will irritate and disturb it, cause it to react, and make a noise and a hissing. This must be understood only of this sort of nitre, of the nitre of the ancients; not of the moderns, which is no other than saltpetre; for though this will ferment with vinegar, saltpetre will not (s): nitre is dissolved by a liquid, but not any, only that which is cold, as Aristotle observes (t), as is vinegar; and therefore, with great propriety, this is joined to what goes before;

so is he that singeth songs to a heavy heart; rather distresses and afflicts him the more; as he cannot sing himself, he cannot bear to hear others sing; such rather should be condoled and wept with than to have songs sung to them. Some understand the words in a sense the reverse; the word rendered taketh away, in the first clause, has the signification of adorning with a garment; hence they render it, "as he that putteth on a garment (u) for ornament in cold weather, and as vinegar to nitre, so is he that singeth songs to a heavy heart"; that is, as an additional garment drives away cold, and vinegar dissolves nitre, so singing songs to a heavy hearted man drives away sorrow; as in the case of Saul, such an effect had music on him, 1 Samuel 16:21; or rather, to put on a thin garment for ornament in cold weather is as absurd and unseasonable as to put vinegar to nitre, or to a wound, as Schultens, and to sing songs to a heavy heart; all absurd.
