When Moshe spent seven days talking with Hashem at the Burning Bush, he learned a great deal about Hashem’s essence. He asked Hashem how he could pass this knowledge on to the people. Hashem’s response was, אהיה אשר אהיה, I am what I am.
The Talmud in מסכת ברכות explains the meaning of this verse. Hashem was saying that He would be with בני ישראל during this difficult period, and He would continue to be with them in future difficulties.
Moshe was not happy with this answer. He told Hashem that he thought it was a bad idea to tell the slave community that they will have other obstacles to overcome in the future. Hashem agreed with Moshe and said, אהיה שלחני אליהם, which means He will be with them now and later deal with the other issues as they come up.
This is a good lesson for us. Don’t become overwhelmed by all of problems we see ahead. Just take it slowly, one problem at a time. And remember that Hashem is always with us.
