71 But the children of Israel committed unfaithfulness in that which had been brought under the curse: Achan, the son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, took of the accursed thing; and the anger of Jehovah was kindled against the children of Israel. 2 And 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 country. And the men went up and spied out Ai. 3 And they returned to Joshua, and said to him, Let not all the people go up; let about two or three thousand men go up and smite Ai; make not all the people to toil thither, for they are few. 4 And there went up thither of the people about three thousand men, but they fled before the men of Ai. 5 And the men of Ai smote of them about thirty-six men; and they pursued them from before the gate to Shebarim, and smote them on the descent. Then the hearts of the people melted, and became as 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.
