The families of the clan of Kehat camped to
the south of the Tabernacle.
Numbers 3:29
Korach, whom we will meet later, as the instigator of the mutiny against the authority of Moses, was a Levite of the tribe of Kehat. Most of his fellow mutineers came from the tribe of Reuben, who also camped south of the Tabernacle, near the clan of Kehat. They were thus exposed to Korach’s negative influence and subsequently got caught up in his mutiny.
Moses and Aaron camped on the east side of the Tabernacle. The tribes of the camp of Judah, who also camped on the east side of the Tabernacle, constantly witnessed Moses’ and Aaron’s devotion to the Torah, and this inspired them to become great Torah scholars themselves.
We learn from this the importance of good neighbors. We can also see that a bad neighbor is one who, like Korach, promotes dissension and discord, while the best possible neighbors are those who, like Moses and Aaron, inspire others to study the Torah, for “its ways are ways of pleasantness and all its paths are peace.”
