'Brother's' in the Bible

And her brother Absalom said to her, Has your brother Amnon been with you? but now, let there be an end to your crying, my sister: he is your brother, do not take this thing to heart. So Tamar went on living uncomforted in her brother's house.

And now all the family is turned against me, your servant, saying, Give up him who was the cause of his brother's death, so that we may put him to death in payment for the life of his brother, whose life he took; and we will put an end to the one who will get the heritage: so they will put out my last burning coal, and my husband will have no name or offspring on the face of the earth.
