Joshua 7:4 So there went up thither of the people about three thousand men: and they fled before the men of Ai.
[Patriarchs & Prophets pp 494] Joshua looked upon their ill success as an expression of God's displeasure, and in distress and apprehension he “rent his clothes, and fell to the earth upon his face before the ark of the Lord until the eventide, he and the elders of Israel, and put dust upon their heads.” “Alas, O Lord God,” he cried, “wherefore hast Thou at all brought this people over Jordan, to deliver us into the hand of the Amorites, to destroy us? ... O Lord, what shall I say, when Israel turneth their backs before their enemies!
For the Canaanites and all the inhabitants of the land shall hear of it, and shall environ us round, and cut off our name from the earth: and what wilt Thou do unto Thy great name?” The answer from Jehovah was, “Get thee up; wherefore liest thou thus upon thy face? Israel hath ... transgressed My covenant which I commanded them.” It was a time for prompt and decided action, and not for despair and lamentation. There was secret sin in the camp, and it must be searched out and put away before the presence and blessing of the Lord could be with His people.
“Neither will I be with you any more, except ye destroy the accursed from among you.” God's command had been disregarded by one of those appointed to execute His judgments. And the nation was held accountable for the guilt of the transgressor: “They have even taken of the accursed thing, and have also stolen, and dissembled also.” Instruction was given to Joshua for the discovery and punishment of the criminal.
Joshua 7:13 Up, sanctify the people, and say, Sanctify yourselves against to morrow: for thus saith the Lord God of Israel, There is an accursed thing in the midst of thee, O Israel: thou canst not stand before thine enemies, until ye take away the accursed thing from among you.
May God add His blessing to the study of His word. “Good night” and God bless!
