'Brother' in the Bible

But he did not invite Nathan the prophet or Benaiah or the mighty warriors or Solomon his brother.

Regarding the sons of Barzillai the Gileadite, you shall do loyal love and let them be among those who eat at your table, because they met me when I fled from Absalom your brother.

Then she said, "Let Abishag the Shunnamite be given to Adonijah your brother as wife."

King Solomon answered and said to his mother, "Why are you asking Abishag the Shunnamite for Adonijah? Ask for him also the kingdom, for he is my brother, older than I; and [ask] for him also Abiathar the priest, and for Joab the son of Zeruiah."

So he said, "What [are] these cities that you have given to me, my brother?" {So they are called the land of Cabul until this day}.

He put his corpse in his tomb, and they mourned over him, "Alas, my brother!"

So they tied sackcloth around their waists and ropes on their heads. Then they went to the king of Israel and said, "Your servant Ben-Hadad says, 'Please let me live.'" And he said, "[Is] my brother still alive?"

The men took this as a good omen and they quickly accepted [it] as true from him, and they said, "Your brother Ben-Hadad [lives]." So he said, "Go, get him." Ben-Hadad came out to him, and [Ahab] pulled him up on the chariot.
