"Rashbam, Rashi's grandson, explains that the word נער, followed by the phrase 'את בני בלהה ואת בני זלפה' (with the sons of Bilhah and the sons of Zilpah) teaches that Yosef 'spent his childhood' with the children of his father's concubines, Bilhah and Zilpah, rather than with Leah's sons. That distance, according to Rashbam, explains Leah's sons' antipathy towards, and ultimately hatred of, Yosef. In this reading, Yosef was despised for whom he happened to hang out with in the play-yard, an explanation that at least partially exonerates Yosef."
WIKIPEDIA: According to the Bible, Galilee was named by the Israelites and was the tribal region of Naphthali and Dan, at times overlapping the Tribe of Asher's land.
