The name Reuben in the Bible
Reuben is the first son of Jacob (Genesis 29:32). His mother is Leah. Reuben forfeits his position as first born when he sleeps with Bilhah, the mother of Jacob's sons number five and six (Genesis 35:22). Reuben's progeny, the ראובני (Reubenites; Numbers 26:7) becomes one of the twelve tribes of Israel.
'...and [Leah] named him Reuben, for she said, "Because the Lord has seen my affliction..."' (Genesis 29:32).
After the conquest of Canaan, the leaders of the tribe of Reuben chose their territory east of the Jordan, together with the tribes of Gad and Manasseh (Numbers 32:33). That forced them to invade the lands of the Ammonites and Moabites and later exposed them to the forces of Assyria (1 Chronicles 5:6, 5:26).
The name Reuben appears only once in the New Testament, in the paragraph in Revelation that deals with the 144,000 sealed Israelites (spelled Ρουβην, Rhouben; Revelation 7:5).
