The Sin of Achan

71 But the Israelites were unfaithful in regard to the devoted things[1] ; Achan son of Karmi, the son of Zimri,[2] the son of Zerah, of the tribe of Judah, took some of them. So the Lord's anger burned against Israel. 2 Now Joshua sent men from Jericho to Ai, which is near Beth Aven to the east of Bethel, and told them, "Go up and spy out the region." So the men went up and spied out Ai. 3 When they returned to Joshua, they said, "Not all the army will have to go up against Ai. Send two or three thousand men to take it and do not weary the whole army, for only a few people live there." 4 So about three thousand went up; but they were routed by the men of Ai, 5 who killed about thirty-six of them. They chased the Israelites from the city gate as far as the stone quarries and struck them down on the slopes. At this the hearts of the people melted in fear and became like water.

Commentary on Joshua 7:1-5

(Read Joshua 7:1-5)

Achan took some of the spoil of Jericho. The love of the world is that root of bitterness, which of all others is most hardly rooted up. We should take heed of sin ourselves, lest by it many be defiled or disquieted, Hebrews 12:15; and take heed of having fellowship with sinners, lest we share their guilt. It concerns us to watch over one another to prevent sin, because others' sins may be to our damage. The easy conquest of Jericho excited contempt of the enemy, and a disposition to expect the Lord to do all for them without their using proper means. Thus men abuse the doctrines of Divine grace, and the promises of God, into excuses for their own sloth and self-indulgence. We are to work out our own salvation, though it is God that works in us. It was a dear victory to the Canaanites, whereby Israel was awakened and reformed, and reconciled to their God, and the people of Canaan hardened to their own ruin.
