Traitor 2

Psalm 55:12-14 - If an enemy were insulting me,
I could endure it;
if a foe were raising himself against me,
I could hide from him.

But it is you, a man like myself,
my companion, my close friend,

with whom I once enjoyed sweet fellowship
as we walked with the throng at the house of God.

I wonder if this is the same traitor mentioned in an earlier psalm (41).
