Exodus 17

"But Moses’ hands became heavy; so they took a stone and put it under him, and he sat on it. And Aaron and Hur supported his hands, one on one side, and the other on the other side; and his hands were steady until the going down of the sun. So Joshua defeated Amalek and his people with the edge of the sword." vv.12-13

Read chapter 17
This is the first time we meet Joshua. Here battling against the Amalekites while Moses is up on a hill with his arms raised to God with the rod in view that God controlled the battle. This was still a pretty intense and long battles as it mentioned it went till sunset. Even though God is fighting for us it's not always a quick win but an enduring victory. It can cause us to grow tired and weary in our daily battles as we see here with Moses. Thankfully he had amazing friends and family who help through this battle in keeping his arms raised to the Lord; Aaron (Moses' brother) and Hur, the architect of the tabernacle (Ex.31:2). The strongest arm or man grows weak, but only God's outstretched arm is held out still. Do you have friends who are accountable and lift your hands up to God? What battle are you fight right now and how have you let the Lord's arms uphold you or how have you grown weary?
