Birthright

Easton's Bible Dictionary (1897)

(1.) This word denotes the special privileges and advantages belonging to the first-born son among the Jews. He became the priest of the family. Thus Reuben was the first-born of the patriarchs, and so the priesthood of the tribes belonged to him. That honour was, however, transferred by God from Reuben to Levi (Num. 3:12, 13; 8:18). (2.) The first-born son had allotted to him also a double portion of the paternal inheritance (Deut. 21:15-17). Reuben was, because of his undutiful conduct, deprived of his birth-right (Gen. 49:4; 1 Chr. 5:1). Esau transferred his birth-right to Jacob (Gen. 25:33). (3.) The first-born inherited the judicial authority of his father, whatever it might be (2 Chr. 21:3). By divine appointment, however, David excluded Adonijah in favour of Solomon. (4.) The Jews attached a sacred importance to the rank of “first-born” and “first-begotten” as applied to the Messiah (Rom. 8:29; Col. 1:18; Heb. 1:4-6). As first-born he has an inheritance superior to his brethren, and is the alone true priest.

Smith's Bible Dictionary (1863)

the advantages accruing to the eldest son. These were not definitely fixed in patriarchal times. Great respect was paid to him in the household, and, as the family widened into a tribe, this grew into a sustained authority, undefined save by custom, in all matters of common interest. Thus the “princes” of the congregation had probably rights of primogeniture. (Numbers 7:2; 21:18; 25:14) (Gradually the rights of the eldest son came to be more definite: (1) The functions of the priesthood in the family with the paternal blessing. (2) A “double portion” of the paternal property was allotted by the Mosaic law. (21:16-17) (3) The eldest son succeeded to the official authority of the father. The first-born of the king was his successor by law. (2 Chronicles 21:3) In all these Jesus was the first-born of the father.
