Did not Achan the sonne of Zerah commit a trespasse in the accursed thing, and wrath fell on all the Congregation of Israel? and that man perished not alone in his iniquitie. Joshua 22:20 (KJV)
The book of Joshua records the events that took place after Moses’ death, as Joshua led the Israelites into the Promised Land. In Joshua 22 the tribes of Reuben, Gad, and half the tribe of Manasseh had been granted land on the east side of the Jordan River. They had fulfilled their commitment to help the other tribes conquer the land west of the Jordan and were now returning home.
“Now be content, my lord the governor; as the LORD has said to us, we will do what He has commanded, and we will not go against the word of the LORD our God.”
Achan’s trespass refers to the incident recorded in Joshua 7. Achan, from the tribe of Judah, took some of the devoted or accursed things from Jericho in direct violation of God’s command. His hidden disobedience caused Israel to suffer a defeat at Ai, and God’s anger was kindled against the whole nation.
The consequences of Achan’s sin are detailed in Joshua 7:19‑21, where the Israelites were defeated and the whole congregation felt the weight of divine wrath. The sin of one individual brought judgment upon all, illustrating how corporate sin can bring collective punishment.
In Joshua 22:20 the western tribes cite Achan’s trespass as a warning to their brethren on the east side of the Jordan. They caution that if the eastern tribes were to rebel against God, the same wrath that fell on the entire congregation because of Achan would again be poured out on all Israel.
The passage teaches several timeless lessons. First, the impact of sin: Achan’s wrongdoing had severe repercussions not only for himself but for the entire nation, reminding believers that personal sin can affect the broader community. Second, obedience to God: the narrative underscores the necessity of faithfully following God’s commands and avoiding hidden compromise. Third, corporate responsibility: the text highlights the interconnectedness of God’s people, urging believers to consider how their choices influence the spiritual health of the whole body.
In summary, Joshua 22:20 serves as a sobering reminder of the seriousness of sin, the importance of unwavering obedience, and the need for vigilance in upholding corporate responsibility within the community of believers.
