GAMALIEL (גַּמְלִיאֵל).  A variant form of Hebrew Gamliel (q.v.), meaning "recompense of God." 

... The word Gamaliel means "recompense, or benefit, of God."  It will be recognised as the name of the distinguished Pharisee and Scribe who, as a member of the Sanhedrim, offered the wise and moderate, though temporizing counsel which had the effect of mitigating the persecution of the apostles by that body, and who was also the theological instructor of St. Paul in the days of his youth, when he "made proficiency in the Jews' religion above many his equals in his own nation," and was doubtless preparing for the office of a Scribe or doctor of the law.  No other persons are called by this name in Scripture.
