Barak and Deborah go up Mount Tabor with 10,000 men as commanded by the Lord.
When they are up there, Sisera is being told: Judges 4:12
And they reported to Sisera that Barak the son of Abinoam had gone up to Mount Tabor.
Sisera comes with his army to defeat Barak, but God has different plans.
Then Deborah said to Barak, “Up! For this is the day in which the Lord has delivered Sisera into your hand. Has not the Lord gone out before you?” So Barak went down from Mount Tabor with ten thousand men following him.
Even though Barak and the Israelites were weak, Barak’s and the Israelite’s obedience gave them a great victory. When we are weak God is strong, obedience is better (for us) than sacrifice.
