The Book of Deuteronomy opens with Moses going over the history of the Jews in the Wilderness. This was to teach us to learn from our mistakes. Great leaders learn from their mistakes.
Now for a quick Devar Torah.
This week’s parashah, Devarim, begins the Book of Deuteronomy. It is always read on the Shabbat before Tisha B’Av because Moses is looking back over Israel’s history. He reminds the people not only of God’s blessings, but also of their failures. Yet the purpose is not to dwell on the past. It is to learn from it.
That is one of the Torah’s greatest lessons. The question is not whether we make mistakes—we all do. The real question is whether we learn from them.
If you look through the Bible, virtually every great leader is flawed. Abraham has moments where he falls short. Moses makes mistakes. King David commits serious sins. The Torah never hides these flaws. Instead, it teaches us that greatness is measured not by perfection but by the willingness to grow.
A good example outside the Torah is George Washington. A new movie, Young Washington, makes the point that Washington was not born the leader we remember today. As a young officer in the French and Indian War, he made serious military mistakes. But he learned from them. Those painful lessons helped shape the commander who would later lead the Continental Army and become America’s first president.
The Torah presents the same contrast through Israel’s first two kings.
King Saul was commanded to destroy Amalek completely. Instead, he spared King Agag and allowed the people to keep the spoils. When the prophet Samuel confronted him, Saul refused to take responsibility. He blamed the people. But the king is responsible for the nation’s decisions. Leadership means that the buck stops with you. Samuel then executed Agag himself. Our tradition teaches that because Agag had been spared even briefly, he fathered descendants, one of whom was Haman, the villain of the Book of Esther.
King David also committed a terrible sin in the episode of Bathsheba. The Midrash relates that David once said that if he had been given Abraham’s tests, he would have passed them. God answered, “I will give you your own test.” David knew temptation was coming, yet he failed.
Afterward, David wished the episode could simply disappear. Instead, God made sure it would remain in the Bible for every generation to read. Why? Not to humiliate David, but to teach us something essential. David admitted his sin. He repented. He accepted responsibility and changed.
That is why David became the model of Jewish kingship. Not because he was perfect, but because when he failed, he did not hide, deny, or blame others. He accepted responsibility and grew from the experience.
As we approach Tisha B’Av, that is the message of Parshat Devarim. Nations, communities, and individuals all make mistakes. The real tragedy is not failing; it is refusing to learn. The path to redemption begins the moment we honestly acknowledge our shortcomings, accept responsibility, and commit ourselves to becoming better.
Something to think about.
