“And Moses built an altar, and called the name of it Jehovah nissi.” Exodus 17:15
The book of Exodus declares the going out of the children of Israel from the land of their bondage; God brings His people out so He might bring them in to the land He promised them.
The scriptures declare there is a war in the process of bringing God’s people out of bondage, in Exodus 17 we are told, “God would make war with Amalek from generation to generation. In this war there is, as in all nations, a standard, or banner by which the troops are rallied. In our county, we have the stars and stripes, which every American is aware, stood through the night, though the bombs were bursting in mid air.
In Israel, each family was to have their own banner, and there was to be a banner on each side of the tabernacle. When Israel camped at Rephidim Amalak made war with them, and at that time, Moses lifted his hand and became the banner for Israel. As God’s man Moses led the people out of Egypt, then in Exodus 17 the sight of him, with his hand raised gave victory to God’s people.
Moses was only a man, and as such, he pointed to the God/man who would one day come and die for the sins of His beloved. Christ sets the captive free, makes their hearts ready for war, and makes clear the enemy.
The Christian is to keep looking unto Jesus the author and finisher of his faith, who for the joy set before Him, endured the cross, and is set down at the right hand of the throne of God.
