'Brethren' in the Bible

Hear a word of Jehovah, Ye who are trembling unto His word, Said have your brethren who are hating you, Who are driving you out, for My name's sake: 'Honoured is Jehovah, and we look on your joy,' But they are ashamed.

And they have brought all your brethren out of all the nations, A present to Jehovah, On horses, and on chariot, and on litters, And on mules, and on dromedaries, Unto My holy mountain Jerusalem, said Jehovah, As the sons of Israel bring the present in a clean vessel, Into the house of Jehovah.
