         patriarchs of Israel

Easton's 1897 Bible Dictionary:

Simeon
   hearing. (1.) The second son of Jacob by Leah (Gen. 29:33). He
   was associated with Levi in the terrible act of vengeance
   against Hamor and the Shechemites (34:25, 26). He was detained
   by Joseph in Egypt as a hostage (42:24). His father, when dying,
   pronounced a malediction against him (49:5-7). The words in the
   Authorized Version (49:6), "they digged down a wall," ought to
   be, as correctly rendered in the Revised Version, "they houghed
   an ox."

     (2.) An aged saint who visited the temple when Jesus was being
   presented before the Lord, and uttered lofty words of
   thankgiving and of prophecy (Luke 2:29-35).

     (3.) One of the ancestors of Joseph (Luke 3:30).

     (4.) Surnamed Niger, i.e., "black," perhaps from his dark
   complexion, a teacher of some distinction in the church of
   Antioch (Acts 13:1-3). It has been supposed that this was the
   Simon of Cyrene who bore Christ's cross. Note the number of
   nationalities represented in the church at Antioch.

     (5.) James (Acts 15:14) thus designates the apostle Peter
   (q.v.).
