YAHVÉ-NISSÍ: GOD, MY BANNER
Biblical Context
This compound name, which we find in Exodus 17:15, has deep meaning in the context of Israel's history and reveals much about the protective and conquering character of GOD.
The name Yahweh-Nissi arises at a crucial time for the people of Israel. They are facing a battle against the Amalekites and need God's help. Moses extends his hands in prayer, and as he holds them up, Israel prevails. But when he lowers his arms, the Amalekites gain ground. Then, Aaron and Hur hold his hands so that Moses does not get tired.
It is in this context of struggle and victory, God tells Moses: “Write this as a memorial in a book, and tell Joshua that I will completely blot out the memory of Amalek from under heaven. And Moses built an altar, and called it Jehovah-Nissi. (Exodus 17:14-16)
Yahvé:
It is a transliteration of the tetragrammaton name YHWH, the proper name of God revealed to Moses. It means "I am that I am" and expresses the self-existence and eternity of God.
It means "flag" or "banner." In ancient times, flags were symbols of protection and leadership.
God as protector:
By calling this altar "Jehovah-Nissi", Moses is declaring that God is his flag, his standard. That is, God is his protection, his strength and his guide in battle.
God as victor:
The name also implies that God is the victor in battle. He has sworn to wage eternal war against the enemies of his people.
A reminder for the future:
The altar of Jehovah-Nissi becomes a memorial for future generations, reminding them that God has always been and always will be their protector and defender. God is not a distant spectator, but fights the "battles" of his children. Being our refuge and strength in times of difficulty. God keeps what he promises and will always be with us.
