A servant who deals wisely will rule over a son who acts shamefully and will share the inheritance as one of the brothers. Proverbs 17:2

continuing:

The crucible is for silver, and the furnace is for gold, and the LORD tests hearts. An evildoer listens to wicked lips, and a liar gives ear to a mischievous tongue. Whoever mocks the poor insults his Maker; he who is glad at calamity will not go unpunished. Proverbs 17:3-5

related:

Whoever troubles his own household will inherit the wind, and the fool will be servant to the wise of heart. Proverbs 11:29

Behold, I have refined you, but not as silver; I have tried you in the furnace of affliction. Isaiah 48:10

Also see Isa. 1, Ezek. 22.

“I have made you a tester of metals among my people, that you may know and test their ways. They are all stubbornly rebellious, going about with slanders; they are bronze and iron; all of them act corruptly. The bellows blow fiercely; the lead is consumed by the fire; in vain the refining goes on, for the wicked are not removed. Rejected silver they are called, for the LORD has rejected them.” Jeremiah 6:27-30

The righteous will never be removed, but the wicked will not dwell in the land. The mouth of the righteous brings forth wisdom, but the perverse tongue will be cut off. The lips of the righteous know what is acceptable, but the mouth of the wicked, what is perverse. Proverbs 10:30-32

Because of the violence done to your brother Jacob, shame shall cover you, and you shall be cut off forever. On the day that you stood aloof, on the day that strangers carried off his wealth and foreigners entered his gates and cast lots for Jerusalem, you were like one of them. But do not gloat over the day of your brother in the day of his misfortune; do not rejoice over the people of Judah in the day of their ruin; do not boast in the day of distress. Do not enter the gate of my people in the day of their calamity; do not gloat over his disaster in the day of his calamity; do not loot his wealth in the day of his calamity. Do not stand at the crossroads to cut off his fugitives; do not hand over his survivors in the day of distress. For the day of the LORD is near upon all the nations. As you have done, it shall be done to you; your deeds shall return on your own head. For as you have drunk on my holy mountain, so all the nations shall drink continually; they shall drink and swallow, and shall be as though they had never been. But in Mount Zion there shall be those who escape, and it shall be holy, and the house of Jacob shall possess their own possessions. The house of Jacob shall be a fire, and the house of Joseph a flame, and the house of Esau stubble; they shall burn them and consume them, and there shall be no survivor for the house of Esau, for the LORD has spoken. Obadiah 1:10-18
