      adj : first in order of birth; "the firstborn child" [syn: eldest]
      n : the offspring who came first in the order of birth [syn: eldest]
 First-born
    sons enjoyed certain special privileges (Deut. 21:17; Gen.
    25:23, 31, 34; 49:3; 1 Chr. 5:1; Heb. 12:16; Ps. 89:27). (See BIRTHRIGHT.)
      The "first-born of the poor" signifies the most miserable of
    the poor (Isa. 14:30). The "church of the first-born" signifies
    the church of the redeemed.
      The destruction of the first-born was the last of the ten
    plagues inflicted on the Egyptians (Ex. 11:1-8; 12:29, 30).
      Menephtah is probably the Pharaoh whose first-born was slain.
    His son did not succeed or survive his father, but died early.
    The son's tomb has been found at Thebes unfinished, showing it
    was needed earlier than was expected. Some of the records on the
    tomb are as follows: "The son whom Menephtah loves; who draws
    towards him his father's heart, the singer, the prince of
    archers, who governed Egypt on behalf of his father. Dead."
