The word of the Lord came again unto me saying, “Moreover, you son of man, take one stick [record] and write upon it, “For Judah, and for the children of Israel his companions;” then take another stick [record], and write upon it, “For Joseph, the stick of Ephraim and for all the house of Israel his companions.” And join them one to another into one stick [combine the records]; and they shall become one in your hand.”
And when the children of your people shall speak unto you, saying, “Will you not show us what you mean by these.” Say unto them, “Thus says the Lord God: Behold I will take the record of Joseph [Book of Mormon], which is in the hand of Ephraim [Restoration], and the tribes of Israel his fellows, and will put them with him, even the record of Judah [Bible] and make them one record and they shall be one in mine hand.”
Ezekiel 37:15-19
