Judges 6:34

31 Joash said to all who stood against him, Will you contend for Baal? Or will you save him? he who will contend for him, let him be put to death while [it is yet] morning: if he be a god, let him contend for himself, because one has broken down his altar.

32 Therefore on that day he named him Jerubbaal, saying, Let Baal contend against him, because he has broken down his altar.

33 Then all the Midianites and the Amalekites and the children of the east assembled themselves together; and they passed over, and encamped in the valley of Jezreel.

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.
