Commentary
5 notes on this verseIron sharpeneth iron,.... A sword or knife made of iron is sharpened by it; so butchers sharpen their knives; so a man sharpeneth the countenance of his friend; by conversation with him; thus learned men sharpen one another's minds, and excite each other to learned studies; Christians sharpen one another's graces, or stir up each other to the exercise of them, and the gifts which are bestowed on them, and to love and to good works.

Iron sharpeneth iron
on Proverbs 27:17-19
Iron sharpeneth iron; so a man sharpeneth the countenance of his friend states friendship's use plainly, that one mind set against another produces an edge neither achieves alone. Whoso keepeth the fig tree shall eat the fruit thereof carries the same principle into labor, diligent care returning its own reward, and applies it to the servant who waits on his master. As in water face answereth to face, so the heart of man to man, closes the triad: people reflect one another, and what a man sees in another's heart is commonly his own looking back.

The proverb expresses the gain of mutual counsel as found in clear, well-defined thoughts. Two minds, thus acting on each other, become more acute. This is better than to see in “sharpening” the idea of provoking, and the point of the maxim in the fact that the quarrels of those who have been friends are bitter in proportion to their previous intimacy.
Iron sharpeneth iron - As hard iron, viz., steel, will bring a knife to a better edge when it is properly whetted against it: so one friend may be the means of exciting another to reflect, dive deeply into, and illustrate a subject, without which whetting or excitement, this had never taken place. Had Horace seen this proverb in the Septuagint translation when he wrote to the Pisos? Ergo fungar vice cotis, acutum Reddere quae ferrum valet, exors ipsa secandi. Hor. Ars. Poet., ver. 304. “But let me sharpen others, as the hone Gives edge to razors, though itself have none.” Francis.
