Matthew Henry on Proverbs 17:3
Note, 1. The hearts of the children of men are subject, not only to God's view, but to his judgment: As the fining-pot is for silver, both to prove it and to improve it so the Lord tries the hearts; he searches whether they are standard or no, and those that are he refines and makes purer, Jer 17:10. God tries the heart by affliction (Psa 66:10, Psa 66:11), and often chooses his people in that furnace (Isa 48:10) and makes them choice. 2. It is God only that tries the hearts. Men may try their silver and gold with the fining-pot and the furnace, but they have no such way of trying one another's hearts; God only does that, who is both the searcher and the sovereign of the heart.
Jamieson-Fausset-Brown on Proverbs 17:3
God only knows, as He tries (Psa 12:6; Psa 66:10) the heart.
John Gill on Proverbs 17:3
The fining pot is for silver, and the furnace for gold,.... Refiners of silver have their fining pots, in which they purify the silver from the dross; and goldsmiths have their crucibles to melt and purify their gold, by which assays of the worth and value of it may be made;

Pro 17:1
A comparative proverb with טוב, pairing with Pro 16:32 :
Better a dry piece of bread, and quietness therewith,
Than a house full of slain beasts with unquietness.
Similar to this in form and contents are Pro 15:16. and Pro 16:8. פּת חרבה is a piece of bread (פת, fem., as Pro 23:8) without savoury drink (Theodotion, καθ ̓ ἑαυτόν, i.e., nothing with it), cf. Lev 7:10, a meat-offering without the pouring out of oil. זבחים are not sacrificial gifts (Hitzig), but, as always, slain animals, i.e., either offerings or banquets of slain beasts; it is the old name of the שׁלמים (cf. Exo 18:12; Exo 24:5; Pro 7:14), part of which only were offered on the altar, and part presented as a banquet…
