John Wesley on Genesis 10:2

Moses begins with Japhet's family, either because he was the eldest, or because that lay remotest from Israel, and had least concern with them, at that time when Moses wrote; and therefore he mentions that race very briefly; hastening to give account of the posterity of Ham, who were Israel's enemies, and of Shem, who were Israel's ancestors: for it is the church that the scripture designed to be the history of, and of the nations of the world only as they were some way or other interested in the affairs of Israel.
