Verse 18

And Joseph went forth with his brethren with the mighty men of Egypt, about six hundred men, and they fought with them in the land of Rameses; and the sons of Jacob at that time again fought with the children of Esau, in the fiftieth year of the sons of Jacob going down to Egypt, that is the thirtieth year of the reign of Bela over the children of Esau in Seir.
