Mitzvah journey complications[1]
שלח-לך אנשים ויתרו את-ארץ כנען אשר-אני נתן לבני ישראל איש אחד איש אחד למטה אבתיו תשלחו כל נשיא בהם
Send for yourselves men who shall scout out the land of Canaan, which I am giving to the Jewish people. You shall send one person per ancestral tribe, the prince [of that tribe][2]
As the Jews were about to enter the land of Israel, they got the idea to send out spies to scout out the land. They wanted to see the quality of the land, and of the people. Hashem told Moshe that this isn’t the Divine will, but if the people insist, it’s up to Moshe[3]. Unfortunately, the mission ended in disaster. The spies came back and gave a slanderous report about the land, causing them to be punished with death, along with that entire generation. The Jews were sentenced to wander the wilderness for forty years. Their children were the ones who merited to finally enter the land.
