Reuben

Reuben or Reuven is a Biblical male first name from Hebrew רְאוּבֵן (Reu'ven), meaning "behold, a son". In the Bible, Reuben was the firstborn son of Jacob.

Variants include Rúben in European Portuguese; Rubens in Brazilian Portuguese; Rubén in Spanish; Rubèn in Catalan; Ruben in Dutch and Armenian; and Rupen/Roupen in Western Armenian.

The form Ruben can also be a form of the name Robin, itself a variation of the Germanic name Robert in several Celtic languages. It preserves the "u" sound from the name's first component "hruod" (compare Ruairí, the Irish form of Roderick).
