Judges 6:33-37

Then all the Midianites, the Amalekites, and the people of the east assembled together; and they crossed over and camped in the Valley of Jezreel.

So the Spirit of the Lord covered Gideon like clothing; and he blew a trumpet, and the Abiezrites were called together to follow him.

And he sent messengers throughout Manasseh, and they also were called together to follow him; and he sent messengers to Asher, Zebulun, and Naphtali, and they came up to meet them. Sign of the Fleece

Then Gideon said to God, “If You are going to save Israel through me, as You have spoken,

behold, I am putting a fleece of wool on the threshing floor. If there is dew on the fleece only, and it is dry on all the ground, then I will know that You will save Israel through me, as You have spoken.”
