Which two towns refused bread to Gideon's exhausted men?

Answer: Succoth and Penuel

Both taunted him. On his return Gideon disciplined Succoth's elders with thorns and briers and pulled down Penuel's tower.

“So Gideon said to the men of Succoth, “Please give my troops some bread, for they are exhausted, and I am still pursuing Zebah and Zalmunna, the kings of Midian.””— Judges 8:5 (BSB)
