'Brothers' in the Bible

Joseph died, as did all his brothers, and all that generation.

It happened in those days, when Moses had grown up, that he went out to his brothers, and looked at their burdens. He saw an Egyptian striking a Hebrew, one of his brothers.

Moses went and returned to Jethro his father-in-law, and said to him, "Please let me go and return to my brothers who are in Egypt, and see whether they are still alive." Jethro said to Moses, "Go in peace."
