'Brother' in the Bible

And the day is, that his sons and his daughters are eating, and drinking wine, in the house of their brother, the first-born.

While this one is speaking another also hath come and saith, 'Thy sons and thy daughters are eating, and drinking wine, in the house of their brother, the first-born.

For thou takest a pledge of thy brother for nought, And the garments of the naked Thou dost strip off.

A brother I have been to dragons, And a companion to daughters of the ostrich.
