Do not be afraid of him for I have handed him over to you

Numbers 21:21-35
Defeat of Sihon and Og.
Sihon would not let Israelite pass through his territory. He mustered his entire army and marched out into the desert against Israel. When he reached Jahaz, he fought with Israel.
The Lord said to Moses,"Do not be afraid of him for I have handed him over to you, with his whole army and his land."
So they struck him down, together with his sons and his while army, leaving them no survivors. And they took possession of his land.
Once again Israel requests safe-passage and is refused, but this time they fight and win. he Amorite King Sihon has taken the lands of Moab and Sihon has taken the lands of Moab and rules from the Arnon in the south to the Jabbok in the north, from his capital city of Heshbon. Continuing north the Israelites defeat Og of Bashan at Edrei.
Why?
Israelite took victory when they entered the land of Sihon and Og. God promised them so they don't need to escape and go away but fight with them.
This is a new generation of Israelite they have army of younger men.
Do not be afraid of them for I have handed him over to you. This is the word of the Lord so do it.
Under the blessing of the Lord, we are brave and with confidence.
How?
May my soul and my heart can hear the word of the Lord to do the right things.
