"The Amalekites came and attacked the Israelites at Rephidim. Moses said to Joshua, 'Choose some of our men and go out to fight the Amalekites. Tomorrow I will stand on top of the hill with the staff of God in my hands'" (Ex 17:9).
Moses' staff represented his vocation as a shepherd. When God first met Moses' in the desert at the burning bush, he told him that he was going to use his staff to perform miracles and bring a people out of slavery. God related to Moses through his vocation as a shepherd.
Moses later faced one of his enemies in the new land, the Amalekites. God told him to go to the top of the mountain and hold his staff up to heaven. As long as his staff was outstretched to heaven, Israel would win the battle. But if it was not uplifted, they would suffer defeat.
"So Joshua fought the Amalekites as Moses had ordered, and Moses, Aaron and Hur went to the top of the hill. As long as Moses held up his hands, the Israelites were winning, but whenever he lowered his hands, the Amalekites were winning." (Ex 17:10-11).
Isn't this an interesting picture? When we raise our "staffs" up to the Lord, He becomes our protector. He is our defender. As long we offer up our staffs before the Lord, He can work through it. He works on our behalf. When we lower it, we lose the blessing of God.
When God told Moses He was going to use his staff to bring a people out of bondage, he first had to lay his staff down on the ground. God changed it into a snake and then God told Moses to pick it up by the tail. God was telling Moses to take authority over the serpent in this prophetic act. When Moses picked up the staff, the scripture tells us it is no longer Moses' staff, but it is now the staff of God.
Friend, the lesson for us is to continually offer up our work lives to the Lord and see His protection and blessing upon us as we continually raise our work to the Lord for His use.
