'Brethren' in the Bible

And Adonijah sacrificeth sheep and oxen and fatlings near the stone of Zoheleth, that is by En-Rogel, and calleth all his brethren, sons of the king, and for all the men of Judah, servants of the king;

Thus said Jehovah, Ye do not go up nor fight with your brethren the sons of Israel; turn back each to his house, for from Me hath this thing been;' and they hear the word of Jehovah, and turn back to go according to the word of Jehovah.
