The reputation of the Philadelphia lawyer dates back to the colonial period, when our legal system was in its infancy and lawyers had to be especially astute. Many noted attorneys seem to have hailed from early Philadelphia, and probably no single lawyer is the source of the term, but several have been suggested. Although not strictly a lawyer, Benjamin Franklin is sometimes claimed to have inspired the expression through his cunning in diplomatic negotiations with the British and French. Another possible source is the Scottish-American Philadelphia attorney Andrew Hamilton, who famously got newspaper publisher John Peter Zenger acquitted of libel charges in 1735, paving the way for the principle of freedom of the press in the process.
If we look for lawyers in Scripture we find quite a few.
Above them all we find G-d:
For the LORD is our judge, The LORD is our lawgiver, The LORD is our king; He will save us-- (Isaiah 33:22)
There is only one Lawgiver and Judge, the One who is able to save and to destroy; but who are you who judge your neighbor? (James 4:12)
The law was given through Moshe (John 1:17) which makes him a law giver as well.
Luke 10:25-28 relates the story of a lawyer who asks Messiah "what shall I do to inherit eternal life?"
As the ultimate authority on the Law as well as the ultimate expression of the Law, Messiah Yeshua Himself is the greatest "lawyer".
To Him be the honor, power, and glory forever. Amen.
