D&C 81

As we have recently been instructed for quorum and group meetings to sit in council, the Lord taught (speaking first of the Prophet) -

"...verily I acknowledge him and will bless him, and also thee, inasmuch as thou art faithful in counsel, in the office which I have appointed unto you, in prayer always, vocally and in thy heart, in public and in private, also in thy ministry in proclaiming the gospel in the land of the living, and among thy brethren.
4 And in doing these things thou wilt do the greatest good unto thy fellow beings, and wilt promote the glory of him who is your Lord.
5 Wherefore, be faithful; stand in the office which I have appointed unto you; succor the weak, lift up the hands which hang down, and strengthen the feeble knees.
6 And if thou art faithful unto the end thou shalt have a crown of immortality, and eternal life in the mansions which I have prepared in the house of my Father."  (Doctrine and Covenants 81:3–6)

I believe this applies to high priests as much as it applied to Frederick G. Williams and other counselors.
