Biblical name for Grandma (5)
I believe the answer is:
moses
'grandma' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for moses that I've seen before include "He parted the Red Sea" , "Mountain climber" , "Great Jewish leader who led the flight from Egypt" , "He led the Jews from bondage in Egypt" , "Liberator" .)
