'Brothers' in the Bible

So Samuel took the horn of oil, anointed him in the presence of his brothers, and the Spirit of the Lord took control of David from that day forward. Then Samuel set out and went to Ramah.

One day Jesse had told his son David: “Take this half-bushel of roasted grain along with these 10 loaves of bread for your brothers and hurry to their camp.

Also take these 10 portions of cheese to the field commander. Check on the welfare of your brothers and bring a confirmation from them.

Saul, your brothers, and all the men of Israel are in the valley of Elah fighting with the Philistines."

David left his supplies in the care of the quartermaster and ran to the battle line. When he arrived, he asked his brothers how they were.

He said, ‘Please let me go because our clan is holding a sacrifice in the town, and my brother has told me to be there. So now, if you are pleased with me, let me go so I can see my brothers.’ That’s why he didn’t come to the king’s table.”

So David left Gath and took refuge in the cave of Adullam. When David’s brothers and his father’s whole family heard, they went down and joined him there.

But David said, “My brothers, you must not do this with what the Lord has given us. He protected us and handed over to us the raiders who came against us.
