The Daily Nosh – Joshua 22:20

Did not Achan the son of Zerah break faith in the matter of the devoted things, and wrath fell upon all the congregation of Israel? And he did not perish alone for his iniquity. – Joshua 22:20
Nosh: In the Achan incident at Ai and the resulting discipline on the entire nation, the people of Israel learned the bitter but important lesson that one man’s sin can seriously and adversely affect the lives and welfare of many others.
