The ancient Israelites knew it well, and their experience is a powerful lesson about faith, doubt, and the persistent shadow of enmity.

According to Legends of the Jews, as retold by Ginzberg, when the protective Clouds of Glory vanished after Aaron’s death, a wave of terror swept through the Israelite camp. These weren't just ordinary clouds; they were a divine shield, a constant reminder of God’s presence and protection. No enemy had dared to approach while they were present. But now? Now they were vulnerable.

And who was waiting in the wings to exploit that vulnerability? None other than Amalek.

Amalek isn't just a name; it's a symbol. A symbol of relentless, opportunistic hatred towards Israel. His actions, Ginzberg tells us, were guided by the twisted legacy of his grandfather, Esau. Remember Esau? He never forgave his brother Jacob (later known as Israel). And on his deathbed, Esau charged Amalek with a dark mission: "Avenge me upon his descendants."

Amalek, ever the pragmatist, asked, "How can I possibly defeat Israel?" Esau’s chilling advice: "Wait for them to stumble. The moment you see them falter, attack!"

And that's exactly what Amalek did. He saw the Israelites question, "Is the Lord among us, or not?" – a moment of doubt, a lapse in faith – and he struck. We see this pattern repeated. When the spies returned from scouting the land and the people cried, "Let us make a captain, and let us return into Egypt," – another moment of despair and lack of trust – Amalek was there, ready for battle.

It's a disturbing pattern, isn’t it? Amalek doesn't fight fair. He doesn't engage in open, honorable combat. He waits for weakness, for moments of doubt, and then he pounces.

The story doesn’t end there. Even in later times, Amalek’s hateful legacy continued. The text describes how, when Nebuchadnezzar marched on Jerusalem to destroy it, Amalek positioned himself just a mile outside the city. His plan? According to Legends of the Jews, he planned to declare support for Israel if they won. But if Nebuchadnezzar prevailed, he would cut off the fleeing Israelites, adding insult to injury with vile insults against God and the people.

Tragically, Nebuchadnezzar was victorious. And Amalek, true to his word, preyed upon the fleeing refugees, embodying the worst kind of opportunism.

What are we to take away from this grim tale? Perhaps it's a reminder that vulnerability invites attack. That doubt weakens our defenses. And that some enemies are relentless, waiting for any opportunity to exploit our weaknesses. It also highlights the importance of faith, and the strength that comes from unwavering trust, even when the protective clouds seem to disappear. Because sometimes, the greatest battles are fought not against external enemies, but against the internal doubts that make us vulnerable in the first place.
