Always wait for victory
20 And when they got up in the morning, they went out into the wilderness of Tekoa. And while they were going out, Jehoshaphat, standing, said: Hear me, Judah and inhabitants of Jerusalem. Believe in Jehovah your God, and you will be safe; believe his prophets, and you will be prospered.
21 And there was counsel with the people, and he appointed some to sing and praise Jehovah, clothed in sacred ornaments, while the armed men went forth, and to say, Praise the Lord, for his mercy endureth for ever.
22 And when they began to sing songs of praise, Jehovah set the ambushes of themselves against the children of Ammon, of Moab, and of mount Seir, which came against Judah, and slew one another.

The reification of God in Exodus 17 as "my standard" ensures the victory of the people of God forever.
The victory in spiritual battles comes when we know that the Lord fights for us. This is what it means to rest in the Lord and wait for his salvation.
These verses allude and reveal the third of the keys of the miraculous salvation of Judah and she is praise. Says verse 22 that when they began to sing songs and praises, the Lord placed ambushes against the sons of Ammon, Moab and Mount Seir, enemies who had come against Judah and were defeated, because there is a power in worship and Praise to the highest. They set their eyes on God, believed his word and the glory of God was poured out in a notorious and miraculous way.
We must keep our eyes on God at all times, not look at our disabilities, but look to the only one who is capable, sovereign and powerful to Jehovah of the armies.
When our eyes are directed to God, He responds in a miraculous and wonderful way, for that reason the answer of God to his people was victory and it is the same answer that God has for you today, if you trust Him.
We should not be intimidated by battles when we trust in God, because He will fight for us.
Let us always ask to be able to look to God in difficult times and we will look at his glory and obtain victory.
We are soldiers of Christ and victory belongs to us forevr.
We must keep our eyes on God at all times, not look at our disabilities, but look at the abilities of God who is omnipotent and keeps his promises forever.
