D&C 38
As the Lord was explaining the purpose for going to the Ohio, He said -
"...for this cause I gave unto you the commandment that ye should go to the Ohio; and there I will give unto you my law; and there you shall be endowed with power from on high;
33 And from thence, whosoever I will shall go forth among all nations, and it shall be told them what they shall do; for I have a great work laid up in store, for Israel shall be saved, and I will lead them whithersoever I will, and no power shall stay my hand." (Doctrine and Covenants 38:32–33)
