Passage
Iron sharpens iron; so a man sharpens his friend’s countenance.
Iron sharpens iron; so a man sharpens his friend’s countenance.
Proverbs 27:15 A continual dropping on a rainy day and a contentious wife are alike:
Proverbs 27:16 restraining her is like restraining the wind, or like grasping oil in his right hand.
Proverbs 27:17 Iron sharpens iron; so a man sharpens his friend’s countenance.
Proverbs 27:18 Whoever tends the fig tree shall eat its fruit. He who looks after his master shall be honored.
Proverbs 27:19 Like water reflects a face, so a man’s heart reflects the man.
The verse centers on "iron", "sharpens", "friend", and "countenance". It is saying that the verse draws attention to "iron" and "sharpens", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "restraining her is like restraining the wind..." into verse 18's "Whoever tends the fig tree shall eat...", so "iron" and "sharpens" belong inside that flow. In Proverbs context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "iron" and "sharpens" with trust shaped by these words, not by a vague optimism outside the passage.
