71 But the people of Israel broke faith in regard to the devoted things, for Achan the son of Carmi, son of Zabdi, son of Zerah, of the tribe of Judah, took some of the devoted things. And the anger of the Lord burned against the people of Israel. 2 Joshua sent men from Jericho to Ai, which is near Beth-aven, east of Bethel, and said to them, "Go up and spy out the land." And the men went up and spied out Ai. 3 And they returned to Joshua and said to him, "Do not have all the people go up, but let about two or three thousand men go up and attack Ai. Do not make the whole people toil up there, for they are few." 4 So about 3,000 men went up there from the people. And they fled before the men of Ai, 5 and the men of Ai killed about thirty-six of their men and chased them before the gate as far as Shebarim and struck them at the descent. And 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.
