'Brother' in the Bible

And [the tribe of the sons of] Judah said to [the tribe of the sons of] Simeon his brother, “Come up with me into my allotted territory, so that we may fight against the Canaanites; and I likewise will go with you into your allotted territory.” So Simeon went with him.

Othniel the son of Kenaz, Caleb’s younger brother, captured it; so he gave him his daughter Achsah as a wife.

Then [the warriors of the tribe of] Judah went with [the warriors of the tribe of] Simeon his brother, and they struck the Canaanites living in Zephath and utterly destroyed it. So the city was called Hormah (destruction).

But when the Israelites cried out to the Lord [for help], the Lord raised up a man to rescue the people of Israel, Othniel the son of Kenaz, Caleb’s younger brother.

So his mother’s relatives spoke all these words concerning him so that all the leaders of Shechem could hear; and their hearts were inclined to follow Abimelech, for they said, “He is our relative.”

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

so that the violence done to the seventy sons of Jerubbaal (Gideon) might come [on the guilty], and that their [innocent] blood might be laid on Abimelech their brother, who had killed them, and on the leaders of Shechem, who strengthened his hands (encouraged him) to kill his brothers.
