604. Why He Waited until the War Against Amalek
Question: Why did he wait until the war against Amalek? The answer is that he saw that when they fall from faith, they have to work by themselves. This is the meaning of “awakening from below.” If they are adhered to Moses, who is regarded as the Torah, through the Torah they can be rewarded with faith. Therefore, he had to go to Moses in order to learn from him the ways of faith.
Moses is called “the faithful shepherd,” the shepherd of faith, since Moses is called “Torah,” as it is written, “Remember the Torah [law] of My servant Moses.” Hence, when they are adhered to Moses, they take strength for faith. This is why he had to go to Moses, so as to receive from him the strength.
