The table of the twelve tribes of Israel

The twelve tribes of Israel were founded by Jacob's twelve sons. An exception to this rule is made for the two sons of Joseph, born in Egypt and adopted by Jacob as his own sons (Genesis 48:5), thus forming two tribes. There would thus be thirteen tribes, but the tribe of Levi is considered separate from the twelve, God having entrusted it with the priesthood between Himself and the people.
In Jacob's day, the expression« the twelve tribes of Israel »The name "Lévi" still includes Levi, while Ephraim and Manasseh are counted together under the name of Joseph. But when Canaan is partitioned, Joseph's sons receive two separate territories.
