'Brothers' in the Bible

Adonijah killed sheep and cattle and fatlings by the stone of Zoheleth, which is beside En Rogel; and he called all his brothers, the king's sons, and all the men of Judah, the king's servants:

Thus says Yahweh, "You shall not go up, nor fight against your brothers, the children of Israel. Everyone return to his house; for this thing is of me."'" So they listened to the word of Yahweh, and returned and went their way, according to the word of Yahweh.
