'Brother' in the Bible

yea, Jehovah saith unto Moses, 'Speak unto Aaron thy brother, and he cometh not in at all times unto the sanctuary within the vail, unto the front of the mercy-seat, which is upon the ark, and he dieth not, for in a cloud I am seen upon the mercy-seat.

'Thou dost not hate thy brother in thy heart; thou dost certainly reprove thy fellow, and not suffer sin on him.

And a man who taketh his brother's wife -- it is impurity; the nakedness of his brother he hath uncovered; childless they are.

except for his relation who is near unto him -- for his mother, and for his father, and for his son, and for his daughter, and for his brother.

'When thy brother becometh poor, and hath sold his possession, then hath his redeemer who is near unto him come, and he hath redeemed the sold thing of his brother;

'And when thy brother is become poor, and his hand hath failed with thee, then thou hast kept hold on him, sojourner and settler, and he hath lived with thee;

thou takest no usury from him, or increase; and thou hast been afraid of thy God; and thy brother hath lived with thee;

'And when thy brother becometh poor with thee, and he hath been sold to thee, thou dost not lay on him servile service;

And when the hand of a sojourner or settler with thee attaineth riches, and thy brother with him hath become poor, and he hath been sold to a sojourner, a settler with thee, or to the root of the family of a sojourner,
