be.kho.rah denotes the status or entitlement of the firstborn, and in plural forms the firstborn animals of a herd or flock.

The term most often concerns the firstborn's status, entitlement, or ordering within a family: it can be sold, assigned, retained, or used to arrange persons by seniority. In plural construct forms, it also identifies the firstborn animals of cattle or flock brought or eaten in the worship setting described by the verses.

   In Genesis 25:31, Genesis 25:33, and Genesis 25:34, the singular form occurs in the exchange in which Jacob asks Esau to sell it, Esau swears and sells it, and then despises it. In Deuteronomy 21:17 the APB renders the clause as the "legal right of the birthright" belonging to the acknowledged firstborn son; Genesis 43:33 uses the construct form in seating the firstborn according to this standing, while 1 Chronicles 5:1 describes it as given to Joseph's sons.

   The plural construct form occurs with cattle and flock in Deuteronomy 12:6, Deuteronomy 12:17, and Deuteronomy 14:23, among items brought or eaten at the chosen place. In Genesis 4:4, Abel brings an offering from the firstborn of his flock.

In the Anselm Project Bible: The APB generally uses "birthright" for the family-status use, including the legal-right clause in Deuteronomy 21:17. For the plural animal use, it renders "the firstborn of your cattle and of your flock" and "the firstborn of his flock"; these are verse-level renderings rather than definitions.
