In the case of Achan's sin God said to Joshua: “Neither will I be with you any more, except ye destroy the accursed from among you.” Joshua 7:12. How does this instance compare with the course pursued by those who will not raise their voice against sin and wrong, but whose sympathies are ever found with those who trouble the camp of Israel with their sins? Said God to Joshua: “Thou canst not stand before thine enemies, until ye take away the accursed thing from among you.” Verse 13. He pronounced the punishment which would follow the transgression of His covenant. 1TT 336.2
Joshua then began a diligent search to find out the guilty one. He took Israel by their tribes, then by their families, and next individually; and Achan was designated as the guilty one. But that the matter might be plain to all Israel, that there should be no occasion given them to murmur and to say that the guiltless was made to suffer, Joshua used policy. He knew Achan was the transgressor and that he had concealed his sin and provoked God against His people. Joshua discreetly induced Achan to make confession of his sin, that God's honor and justice might be vindicated before Israel. “And Joshua said unto Achan, My son, give, I pray thee, glory to the Lord God of Israel, and make confession unto Him; and tell me now what thou hast done; hide it not from me. 1TT 337.1
“And Achan answered Joshua, and said, Indeed I have sinned against the Lord God of Israel, and thus and thus have I done: When I saw among the spoils a goodly Babylonish garment, and two hundred shekels of silver, and a wedge of gold of fifty shekels weight, then I coveted them, and took them; and, behold, they are hid in the earth in the midst of my tent, and the silver under it. So Joshua sent messengers, and they ran unto the tent; and, behold, it was hid in his tent, and the silver under it. And they took them out of the midst of the tent, and brought them unto Joshua, and unto all the children of Israel, and laid them out before the Lord. And Joshua, and all Israel with him, took Achan the son of Zerah, and the silver, and the garment, and the wedge of gold, and his sons, and his daughters, and his oxen, and his asses, and his sheep, and his tent, and all that he had: and they brought them unto the Valley of Achor. And Joshua said, Why hast thou troubled us? the Lord shall trouble thee this day. And all Israel stoned him with stones, and burned them with fire, after they had stoned them with stones.” Verses 19-25. 1TT 337.2
The Lord told Joshua that Achan had not only taken the things which He had positively charged them not to take, lest they be accursed, but he had stolen and had also dissembled. The Lord said that Jericho and all its spoils should be consumed, except the gold and silver, which were to be reserved for the treasury of the Lord. The victory of taking Jericho was not obtained through warfare or the exposure of the people. The Captain of the Lord's host had led the armies of heaven. The battle was the Lord's; it was He who fought the battle. The children of Israel did not strike a blow. The victory and glory were the Lord's, and the spoils were His. He directed all to be consumed except the gold and silver, which He reserved for His treasury. Achan understood well the reserve made and that the treasures of gold and silver which he coveted were the Lord's. He stole from God's treasury for his own benefit. 1TT 338.1
