Final answer:
Joshua stood up to slay and destroy the inhabitants of Mount Seir.
Step-by-step explanation:
The biblical book of Judges describes how the Hebrews, under the leadership of different individuals such as Samson and Jepthah, fought against their enemies and conducted acts of violence. However, in this case, the answer to the question of who stood up to slay and destroy the inhabitants of Mount Seir would be Joshua. According to the Book of Joshua, with the help of the Lord, Joshua utterly destroyed several nations and their inhabitants, including the Gibeonites, Makkedah, Libnah, Eglon, Hebron, and Debirites.
