'Brethren' in the Bible

My brethren have dealt deceitfully as a brook, As the channel of brooks that pass away;

He hath put my brethren far from me, And mine acquaintance are wholly 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 concerning all the evil that Jehovah had brought upon him: every man also gave him a piece of money, and every one a ring 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.
