'Brethren' in the Bible

My brethren have dealt deceitfully as a brook, and as the stream of brooks they pass away;

He hath put my brethren far from me, and mine acquaintance are verily estranged from me.

Then came there unto him all his brethren, and all his sisters, and all they that had been of his acquaintance before, and did eat bread with him in his house: and they bemoaned him, and comforted him over all the evil that the LORD had brought upon him: every man also gave him a piece of money, and every one an earring of gold.

And in all the land were no women found so fair as the daughters of Job: and their father gave them inheritance among their brethren.
