71 But the children of Israel committed a trespass in the devoted things; for Achan, the son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, took some of the devoted things. Therefore Yahweh’s anger burned against the children of Israel. 2 Joshua sent men from Jericho to Ai, which is beside Beth Aven, on the east side of Bethel, and spoke to them, saying, “Go up and spy out the land.”
The men went up and spied out Ai. 3 They returned to Joshua, and said to him, “Don’t let all the people go up; but let about two or three thousand men go up and strike Ai. Don’t make all the people to toil there, for there are only a few of them.” 4 So about three thousand men of the people went up there, and they fled before the men of Ai. 5 The men of Ai struck about thirty-six men of them, and they chased them from before the gate even to Shebarim, and struck them at the descent. The hearts of the people melted, 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.
