Joshua 10:24 קְצִינֵ֞י [the] commanders of

When they had brought the kings to Joshua, he summoned all the men of Israel and said to the army commanders who had accompanied him, “Come here and put your feet on the necks of these kings.” So the commanders came forward and put their feet on their necks.

Here: "Chiefs/commanders of". It is a fairly rare word for someone in charge, here the field officers. They are leaders, not ordinary soldiers, so the gesture is carried out by Israel's representatives.

Judges 11:6 לְקָצִ֑ין <into> a commander

“Come,” they said, “be our commander, so that we can fight against the Ammonites.”

Judges 11:11 וּלְקָצִ֑ין and into commander

So Jephthah went with the elders of Gilead, and the people made him their leader and commander. And Jephthah repeated all his terms in the presence of the LORD at Mizpah.

Here: The title the elders first offered (v.6), apparently a war commander or a chief for the emergency. Jephthah ends up with both titles, the first offer and the improved one.

Proverbs 6:7 קָצִ֗ין [is] commander of

Without a commander, without an overseer or ruler,

Here: A person with the authority to decide and command: a war leader or a civic head. The first of three authority figures the ant lacks; it pictures the one who gives orders and settles matters.

Proverbs 25:15 קָצִ֑ין a ruler

Through patience a ruler can be persuaded, and a gentle tongue can break a bone.

Here: A person in authority, especially a military or civic leader (Jephthah is made qatsin in Judges 11). It is not the usual word for king. Here it stands for any powerful superior you cannot force, someone whose anger is dangerous.

Isaiah 1:10 קְצִינֵ֣י O rulers of

Hear the word of the LORD, you rulers of Sodom; listen to the instruction of our God, you people of Gomorrah!

Here: 'Chiefs of': the men who hold command and the power to make decisions, including military leaders and judges. These are Jerusalem's ruling class, the people responsible for justice (see vv. 17, 23).

Isaiah 3:6 קָצִ֖ין a ruler

A man will seize his brother within his father’s house: “You have a cloak—you be our leader! Take charge of this heap of rubble.”

Isaiah 3:7 קְצִ֥ין a ruler of

On that day he will cry aloud: “I am not a healer. I have no food or clothing in my house. Do not make me leader of the people!”

Isaiah 22:3 קְצִינַ֥יִךְ rulers your

All your rulers have fled together, captured without a bow. All your fugitives were captured together, having fled to a distant place.

Daniel 11:18 קָצִ֤ין a commander

Then he will turn his face to the coastlands and capture many of them. But a commander will put an end to his reproach and will turn it back upon him.

Micah 3:1 וּקְצִינֵ֖י and O rulers of

Then I said: “Hear now, O leaders of Jacob, you rulers of the house of Israel. Should you not know justice?

Here: A qatsin is a man with authority to decide, a military commander or magistrate (Josh 10:24; Judg 11:6; Isa 1:10). The word is probably related to Arabic qāḍī, "judge". It stands in parallel with "heads", and together the two words name the ruling class.

Micah 3:9 וּקְצִינֵ֖י and O rulers of

Now hear this, O leaders of the house of Jacob and rulers of the house of Israel, who despise justice and pervert all that is right,

Here: 'And commanders of', meaning people with authority to decide matters, whether military or judicial. It is paired with 'heads' to cover the whole ruling class.
