After they all sang to thank Hashem for saving them. That's why this topic is called "שירת הבאר".
Wow guys look the well of מרים overflowed and what is this it carried weapons all the way here from the top of those mountains. The אמורים must have been trying to attack us, and Hashem saved us.
I'm סיחון the king of אמור and בנ"י can NOT enter the land. Because all the kings of כנען paid me to protect them, and in return I promised not to let other nations come through the land. You know what let's attack them!
Hashem said that we would win and we did. All I had to do was say Hashem's 4 letter name and סיחון died. Also while the nation was busy fighting Hashem made the sun stay out until the fighting was over! The only down side is that when עוג the king of בשן found out he started preparing for av war against us.
עוג was over 500 years old and in his life he did 2 major מצות. The first one was that he ran to tell אברהם that לוט was captured. The second one is that he got a ברית מילה. Since he did those 2 מצות I was afraid that Hashem wouldn't let us defeat him. It turns out that he did those מצות for the wrong reasons and so thats why Hashem let us win. When עוג picked up a small mountain and was holding it over his head ready to throw it at me Hashem made a miracle and saved me. He made ants come and eat the inside if the mountain and they עוג dropped it on his head and it got stuck. Then I stabbed his ankle with an axe and he fell and died.
