were specially learned in the Mosaic Law, and who 
interpreted that Law, and taught it to the people.
They are met with again and again in the Gospels, where they 
frequently came into contact with Christ, usually in a 
manner hostile to Him. For example, "A certain lawyer stood 
up and made trial of him, saying, Teacher, what shall I do 
to inherit eternal life?" (Lk 10:25). our Lord replied to

how readest thou?" Regarding this class of teachers as a

rejected for themselves the counsel of God" (Lk 7:30). The 
term nomikos, "lawyer," applied to Zenas, is in the Gospels 
varied by nomodidakalos, "a teacher of the law," and by 
grammateus, "a scribe": all three terms describe the same
