'Pre eminence' in the Bible

“Reuben, you are my firstborn;My might, the beginning of my strength and vigor,Preeminent in dignity and preeminent in power [that should have been your birthright].

“But unstable and reckless and boiling over like water [in sinful lust], you shall not excel or have the preeminence [of the firstborn],Because you went up to your father’s bed [with Bilhah];You defiled it—he went up to my couch.
