The Israelites do evil, and God delivers them to the Midianites
61 The Israelites did evil in the sight of the Lord, and the Lord delivered them to Midian for seven years. 5 The Midianites were as numerous as grasshoppers, and they had more camels than could be counted. The Israelites were impoverished by the Midianites, so they cried to the Lord.
The call of Gideon
11 An angel of the Lord sat under an oak tree, while Gideon threshed wheat by the winepress.
Show me a sign that it's really you who is talking to me.
18 Stay here until I come back and bring you a present.
The angel said,
OK. I'll stay here until you come back.
19 Gideon went home and killed a young goat, made some cakes, put the flesh in a basket, the broth in a pot, and brought it all out to the oak tree and presented it to the angel.
25 Take your father's young bullock, the one that's seven years old, and throw down the altar of Baal and the grove that is next to it.
26 And build an altar to me on the top of the rock. Then take a second bullock and offer me a burnt sacrifice with the wood that you cut down from the grove.
27 So Gideon took ten men and did as God commanded that night.
28-30 The next day, when the men of the city saw what Gideon had done, they said to Joash, Gideon's father,
Bring out your son so we can kill him, because he knocked down the altar of Baal and cut down the grove.
I'd like you to prove to me that you will use me to save Israel.
37 So I'll put out a fleece of wool on the ground, and if the dew is on the fleece only and the ground beside it is dry, then I'll know that you will save Israel through me, as you said.
The next morning the fleece was dry, and the ground was wet.
A few more words about this episode
The Midianites were as numerous as grasshoppers (6:5)
Every male Midianite was killed during the time of Moses (Numbers 31:7, Episode 68), and yet 200 years later they flourish like grasshoppers "without number."
I'd like you to prove to me that you will use me to save Israel. (6:36)
