Judges 6:39

34 But the Spirit of Yahweh came on Gideon; and he blew a trumpet; and Abiezer was gathered together after him.

35 He sent messengers throughout all Manasseh; and they also were gathered together after him: and he sent messengers to Asher, and to Zebulun, and to Naphtali; and they came up to meet them.

36 Gideon said to God, If you will save Israel by my hand, as you have spoken,

37 behold, I will put a fleece of wool on the threshing floor; if there be dew on the fleece only, and it be dry on all the ground, then shall I know that you will save Israel by my hand, as you have spoken.

38 It was so; for he rose up early on the next day, and pressed the fleece together, and wrung the dew out of the fleece, a bowl full of water.

39 Gideon said to God, Don`t let your anger be kindled against me, and I will speak but this once: Please let me make a trial just this once with the fleece; let it now be dry only on the fleece, and on all the ground let there be dew.

40 God did so that night: for it was dry on the fleece only, and there was dew on all the ground.
