JEHOVAH NISSI

"Adonai said to Moshe, 'Write this in a book to be remembered, and tell it to Y’hoshua: I will completely blot out any memory of ‘Amalek from under heaven.' Moshe built an altar, called it Adonai Nissi [Adonai is my banner/miracle], and said, “Because their hand was against the throne of Yah, Adonai will fight ‘Amalek generation after generation.’”
Exodus 17:14-16

Remember the movie Glory? The movie itself is based on the letters of Colonel Robert Gould Shaw, the commander of the first black regiment in the United States Army. In the final scenes of the movie, the heroic charge of Shaw’s Massachusetts 54th regiment on Fort Wagner is recreated. In a speech given before the dawn attack, Shaw points to the regiment's standard-bearer and said to the men, "If this man should fall, who will lift the flag and carry it on?"
Thomas Earl, known from the letters as a weak and terrible soldier, boldly steps forward and declares, "I will!" As the fight ensues that night, Shaw is found dead. The standard is not picked up by Earl, who had found courage that morning to declare his stance, but rather by Private Tripp, a soldier who had previously deserted his regiment. The letters of Colonel Shaw were written as not only his personal memories, but as a story that years later we could still find courage in.
Moshe had his own story like Colonel Shaw. In Exodus 17, the Torah records Moshe leading the people of Isra’el against the ‘Amalek. Hur, Aharon, and Moshe stood on the top of the hill, while Y’hoshua and his chosen men defended themselves against ‘Amalek. As long as Moshe’s hands were raised, Isra’el won the battle. When Moshe’s arms grew tired and weak, Hur and Aharon held them up. While this is a great illustration of accountability, it is also a great illustration of Adonai as our banner.
Neither Moshe, Y’hoshua, nor anyone in Adonai's army raised a flag as we know it, but when the battle was over and the army of Isra’el was victorious, two actions were completed. First was, Adonai told Moshe to write this down as a memory for Y’hoshua, which is now a memory also for us. The second thing, however, was that Moshe built an altar to Adonai, naming it Adonai-Nissi (Adonai is my Banner). The word Nissi is defined in the Strong's as: flag, sail, flagstaff, signal, and standard. In that moment, Adonai proved Himself to Isra’el as their standard, their flag. As a tribute to Him, they built their altar and named it for who Adonai was in that moment.
We are like Moshe, and ‘Amalek is our enemy. The enemy rises up against us and throws attacks our way. Be it drugs, porn, bitterness, sickness, depression, financial hardship, low self-esteem, the list is endless, but the answer is the same. We stand under Adonai-Nissi. We stand under the flag of who Adonai is. In these moments, call upon Adonai-Nissi. Raise your hands like Moshe; stand with others who will hold you up if needed, but do not give up. Do not let the standard fall to the ground.

Exodus 17:1-15
