Judges 6:36

³⁴  But the Spirit of the LORD came upon Gideon, and he blew a trumpet; and Abiezer was gathered after him.

³⁵  And he sent messengers throughout all Manasseh; who also was gathered after him: and he sent messengers unto Asher, and unto Zebulun, and unto Naphtali; and they came up to meet them.

³⁶  And Gideon said unto God, If thou wilt save Israel by mine hand, as thou hast said,

³⁷  Behold, I will put a fleece of wool in the floor; and if the dew be on the fleece only, and it be dry upon all the earth beside, then shall I know that thou wilt save Israel by mine hand, as thou hast said.

³⁸  And it was so: for he rose up early on the morrow, and thrust the fleece together, and wringed the dew out of the fleece, a bowl full of water.
