'Brother' in the Bible

And Moses sent for Mishael and Elzaphan, the sons of Uzziel, the brother of Aaron's father, and said to them, Come near and take your brothers away from before the holy place, outside the tent-circle.

And the LORD said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the vail before the mercy seat, which is upon the ark; that he die not: for I will appear in the cloud upon the mercy seat.

Thou shalt not uncover the nakedness of thy father's brother, thou shalt not approach to his wife: she is thine aunt.

You are not to have sexual intercourse with your brother’s wife; it will shame your brother.

Thou shalt not hate thy brother in thine heart: thou shalt in any wise rebuke thy neighbour, and not suffer sin upon him.

And if a man has sex relations with the wife of his father's brother, he has put shame on his father's brother: their sin will be on them; till the day of their death they will have no children.

If a man marries his brother’s wife, it is impurity. He has shamed his brother; they will be childless.

But for his kin, that is near unto him, that is, for his mother, and for his father, and for his son, and for his daughter, and for his brother,

If you make a sale to your fellow citizen or buy from your fellow citizen, no one is to wrong his brother.

If thy brother be waxen poor, and hath sold away some of his possession, and if any of his kin come to redeem it, then shall he redeem that which his brother sold.

And if thy brother be waxen poor, and fallen in decay with thee; then thou shalt relieve him: yea, though he be a stranger, or a sojourner; that he may live with thee.

Take thou no usury of him, or increase: but fear thy God; that thy brother may live with thee.

And if thy brother that dwelleth by thee be waxen poor, and be sold unto thee; thou shalt not compel him to serve as a bondservant:

You may give them as inheritance to your children after you to possess as property. You may enslave them perpetually. However, as for your brothers the Israelites, no man may rule over his brother harshly.

And if a sojourner or stranger wax rich by thee, and thy brother that dwelleth by him wax poor, and sell himself unto the stranger or sojourner by thee, or to the stock of the stranger's family:

Or his father's brother, or the son of his father's brother, or any near relation; or if he gets money, he may make himself free.
