'Brothers' in the Bible

Then Samuel took the horn of oil, and anointed him in the midst of his brothers: and the Spirit of Yahweh came mightily on David from that day forward. So Samuel rose up, and went to Ramah.

Jesse said to David his son, "Now take for your brothers an ephah of this parched grain, and these ten loaves, and carry [them] quickly to the camp to your brothers;

and bring these ten cheeses to the captain of their thousand, and see how your brothers are doing, and bring back news."

David left his baggage in the hand of the keeper of the baggage, and ran to the army, and came and greeted his brothers.

He said, 'Please let me go, for our family has a sacrifice in the city. My brother has commanded me to be there. Now, if I have found favor in your eyes, please let me go away and see my brothers.' Therefore he has not come to the king's table."

David therefore departed there, and escaped to the cave of Adullam. When his brothers and all his father's house heard it, they went down there to him.

Then David said, "You shall not do so, my brothers, with that which Yahweh has given to us, who has preserved us, and delivered the troop that came against us into our hand.
