tribe of Zebulun
The tenth son of Jacob by Leah (Gen. Gen. 30:20). Zebulun means dwelling or habitation.
tribe of Joseph
The eleventh son of Jacob by Rachel (Gen. Gen. 30:24). Joseph means adding. One of Josephs sons, Ephraim, is not mentioned in the list of those sealed although Manasseh is. This may not be significant since the tribe of Joseph would normally denote both Manasseh and Ephraim. See commentary on Revelation 7:4.
tribe of Benjamin
The twelfth and last son of Jacob by Rachel (Gen. Gen. 35:18). Joseph means son of my right hand.
