Numbers 16:22

And they fell upon their faces, in the attitude of most fervent intercession, and said, O God, the God of the spirits of all flesh, Creator and Preserver of all living things, shall one man (Korah) sin, and wilt Thou be wroth with all the congregation? Korah was the leading spirit, he had instigated the rebellion; the rest were guilty indeed, but only inasmuch as they had given heed to his seditious speeches. Apparently the Lord heard the prayer of His servants, for He did not proceed to exterminate all the people. The confident prayer of the believers is a mighty weapon before God.
