Proverbs 17:3 uses the same crucible/furnace image for testing, but says the LORD tests the heart — complementing the test by praise.

1 Samuel 18:7 illustrates how praise tested Saul — the women's song praising David more than Saul exposed Saul's jealous heart.

In 1 Samuel 18:8, Saul's jealous rage at David's praise exemplifies how praise tests a person's heart — he failed.

Psalm 66:10 says God tests people like silver is tried — directly applying the refining metaphor to divine testing, parallel to the testing here.

Zechariah 13:9 depicts God refining a remnant like silver — the same crucible/fire imagery for testing and purification.

Malachi 3:3 describes the Lord as a refiner and purifier of silver — a direct parallel to the crucible/furnace testing metaphor here.

1 Peter 1:7 links tested faith by fire to praise — echoing the refining metaphor, while Proverbs says praise itself tests a man.
