, "The first gathering of Israel was done under the direction of Moses and resulted in the exodus from Egypt. Moses therefore holds the keys of the gathering of Israel. The Lord set His hand again the second time to recover the remnant of His people by sending Moses to confer the keys of his authority upon Joseph Smith and Oliver Cowdery in the Kirtland Temple on April 3, 1836." (See D&C 110:11.) 

"We know keys of 50 are with the Top Quorum passed from Joseph"

The Political Kingdom of God

Bruce R. McConkie. in the Millennial Messiah page 362 alludes to this action where it states:-

There is only one presiding prophet on the earth at any one time, And he is the President of the church. All other prophets are subject to him and his direction. There is not now on earth and there shall not be – as long as the earth shall stand or there is one man on the face thereof – a prophet who is not subject to and whose acts are not governed by the presiding prophet.

 Who, then, shall the prophets be among the Ten Tribes? They shall be the worthy and faithful members of the great latter-day kingdom who serve as all faithful elders now serve. Thus saith the Lord:” It shall not be given to anyone to go forth to preach my gospel or build up my church, EXCEPT HE BE ORDAINED BY SOMEONE WHO HAS AUTHORITY and it is known to the church that he has authority and has been regularly ordained by the heads of the church.” D&C42: 11.
