'Brother' in the Bible

Judah said to his brother Simeon, “Come with me to my territory, and let us fight against the Canaanites. I will also go with you to your territory.” So Simeon went with him.

So Othniel son of Kenaz, Caleb’s youngest brother, captured it, and Caleb gave his daughter Achsah to him as his wife.

Judah went with his brother Simeon, struck the Canaanites who were living in Zephath, and completely destroyed the town. So they named the town Hormah.

The Israelites cried out to the Lord. So the Lord raised up Othniel son of Kenaz, Caleb’s youngest brother, as a deliverer to save the Israelites.

His mother’s relatives spoke all these words about him in the presence of all the lords of Shechem, and they were favorable to Abimelech, for they said, “He is our brother.”

and now you have attacked my father’s house today, killed his 70 sons on top of a large stone, and made Abimelech, the son of his slave, king over the lords of Shechem ‘because he is your brother’—

Then Jotham fled, escaping to Beer, and lived there because of his brother Abimelech.

so that the crime against the 70 sons of Jerubbaal might come to justice and their blood would be avenged on their brother Abimelech, who killed them, and on the lords of Shechem, who had helped him kill his brothers.
