Genesis 49:4

Grow thou not. This was not meant by way of a curse or imprecation; but by way of a prophecy, foretelling that the tribe of Ruben should not inherit the pre-eminences usually annexed to the first birth-right, viz., the double portion, the being prince or lord over the other brethren, and the priesthood: of which the double portion was given to Joseph, the princely office to Juda, and the priesthood to Levi. (Challoner) --- Thou hast abandoned thyself to thy brutal passion; do so no more, ne adjicias. (St. Jerome, q. Heb.) Let Ruben live, and die not; let him be small in number, Deuteronomy xxxiii. 6. His tribe never became very considerable. (Calmet) --- Couch. See chap xxxv. 22. Eternal infamy attends the name of Ruben. (Haydock)
