We have little information about Shamgar.
What we do know from His story is God can take something ordinary and use it for the extraordinary.
After Ehud and Shamgar, God calls Deborah to be judge over Israel.
She is the only female judge and the first judge to be called a prophet.
Deborah would not be the only one used to free the Israelites from their oppressors.
Deborah and Barak remind us that God uses multiple people together to see His will done.
