'Brothers' in the Bible

Then Samuel took the horn of oil and anointed him in the midst of his brothers; and the Spirit of the Lord came mightily upon David from that day forward. And Samuel arose and went to Ramah.

Then Jesse said to David his son, “Take now for your brothers an ephah of this roasted grain and these ten loaves and run to the camp to your brothers.

Bring also these ten cuts of cheese to the commander of their thousand, and look into the welfare of your brothers, and bring back news of them.

Then David left his baggage in the care of the baggage keeper, and ran to the battle line and entered in order to greet his brothers.

for he said, ‘Please let me go, since our family has a sacrifice in the city, and my brother has commanded me to attend. And now, if I have found favor in your sight, please let me get away that I may see my brothers.’ For this reason he has not come to the king’s table.”

So David departed from there and escaped to the cave of Adullam; and when his brothers and all his father’s household heard of it, they went down there to him.

Then David said, “You must not do so, my brothers, with what the Lord has given us, who has kept us and delivered into our hand the band that came against us.
