v1: The fourth cycle began (see 2.11-13); this time when the Israelites disobeyed God, He gave them into the hand of Midian for seven years. (The origin of Midian is found in Gen 25.)
v2: The oppression under Midian was so bad that the people hid in the mountains.
v3-6: Midian targeted the Israelites' crops, by ruining them, and by killing livestock as well as people. See Lev 26.16; Deut 28.30-31; the people really could not complain, as these things simply fulfilled what God had warned if they disobeyed. Things were so bad that Israel cried to the Lord God for help.
v7-10: The Lord God sent a prophet to the people, to declare to them their sins. They had to realise that they were actually responsible for their suffering. We see that such a message is important, as it encourages repentance.
v11: Following the prophet, God sent an angel. He came to Gideon, who was threshing wheat in a winepress. This was to keep it from the marauding Midianites. The amount of wheat that would fit in a winepress would have been small, but at least he had something.
v12: The first message, "The Lord is with you"; a message of encouragement. Sometimes this is all we need to know. Sometimes, we need to be reminded of this important truth before any instructions can be given. Gideon would not have thought of himself as a mighty warrior (see v15), but he certainly would become one.
v13: Gideon's response was understandable, but it was to do with sight not faith. Surely God would continue to display His power by signs and wonders. He did not realise that the oppression and suffering were because of Israel's disobedience. Later he desired a sign.
We should not be too critical of Gideon; he thought that God had "abandoned" His people, and he needed to be convinced otherwise. It is God's grace that He should continue to deal with Gideon, and to use him. The indications are that few were as faithful as Gideon; others had worshipped idols.
v14: Following the word of God's presence, there is a commission and a command for Gideon. Although God had an army of angels available, He chose a man; the weak things of the world to put to shame the mighty. The strength Gideon had was, on the one hand nothing (v15), but on the other hand, God was sending him, and therefore victory was certain.
v15-18: Like Moses and Barak and Jeremiah, Gideon was reluctant. God was gracious, and gave a sign to encourage him. There is a distinction to be made between reluctance and an excuse for disobedience (see Luke 9.57-62; 14.15-24).
v19: Given that the harvest was small, and most of the livestock was dead, Gideon's offering was costly. This was a further indication of his love for God; imperfect understanding, but a real and growing devotion to God. God is looking for willing volunteers, not pressed men (see also 7.1-8). Where we choose to honour God, He will bless us and use us.
v20-24: When Gideon made His offering, God gave a sign, to further encourage him; the bread and meat was consumed in the flame. Gideon built an altar to God, Yahweh Shalom (v24). This was a real testimony, as an altar would be seen by others.
v25-27: A test of loyalty; the Lord's instructions, that Gideon destroy his father's altar, the family idol, and replace it with an altar to the true God. Although Gideon was fearful, and worked at night, he obeyed the command. This action was necessary before he could think of attacking Midian. Israel could not expect to win a battle if they maintained idolatry.
v30-32: The people quickly found out about Gideon; but his father, Joash, intervened. Although it was his idol, he was loyal to his son, and was perhaps impressed by his commitment. Surely Baal could defend himself!
v33-34: It seems at the same time, there was a fresh attack form Midian. This gave the opportunity for Gideon to gather the people of Abiezer together to fight.
v36-40: Gideon asked for more signs, which God gave. He understands our frame, and remembers that we are dust. Although God had already spoken and promised victory, Gideon needed encouragement, and God gave it.
