In Exodus 17, after the defeat of the Amalekites, Moses builds an altar and named it Yahweh-nissi, which means “the LORD is my banner.” This may seem strange for us to embrace personally, unless we have a good understanding of a banner. When we think banner, we think of something posted at a convention or bazaar.
Think of a banner as the flag taken into battle. To the army, the flag is a great symbol. This shows the side of who you are fighting. This is a symbolization of strength and security. If you are defeated, the flag is taken. Think of capture the flag. The flag is also a place to rally. One would return to the flag, the rally point, after battle. Consider a sporting event, where the individual teams or schools are represented at different rally points. A person knows where to find their teammates when they find their flag. The banner is also lifted high. This is important to the battle against the Amalekites. Remember, as long as Moses raised the banner high, the Israelites were winning. Lifting the flag high was a great symbol against the Amalekites. It showed all that it was in fact the Lord fighting this battle—He was bringing victory for His chosen people.
What can we take away from this? How is the Lord our personal Banner? He is our strength and our security. It is at His altar that we can fall and find comfort in His strength and His security. As well, it is at His altar that we find safety—He is our rally point. We are meant to run to Him. Just as Moses lifted high the banner during the battle, so we lift Jesus high. We lift our hands to Him. We raise our voices to Him. When we think upon these things, it is then that we can embrace Yahweh-nissi. The LORD is my banner.
“Moses built an altar there and named it Yahweh-nissi (which means “the LORD is my banner”).” – Exodus 17:15 [NLT]
