How was the gift of the word of knowledge defined by the pioneers of the pentecostal healing revival I will ask a series of questions concerning individual spiritual gifts (pneumatika/charismata), or manifestations of the Spirit in 1 Cor 12.

This second one is also about the gift of the word (logos) of knowledge (gnosis) (1 Cor 12:8), and it is closely related to the first one.

How did the pioneers of the healing revival (Branham/Coe/Roberts/etc) speak about this specific gift, e.g in the Magazine The Voice of Healing or in their sermons or testimonies?
W. V. Grant wrote in THE VOICE OF HEALING October 1953 Page 24 about the word of knowledge.


  WHAT IT IS
  
  The Spiritual gift of the word of knowledge is certain
  facts in the mind of God, which He sees fit to reveal to a servant
  supernaturally by His Spirit. It is only a “word,” or a portion of
  God's great storehouse of knowledge. God speaks in divers manners,
  such as dreams, visions, revelation, or in audible voice. It is always
  conveyed supernaturally as any other gift. This gift can tell the
  whereabouts, conditions, nature, or thoughts of a person, animal,
  place, or thing even when it is impossible to learn it in the natural.
  
  It is different from the Spiritual gift of faith in that it lets you
  know things even when you did not pray for them. The Spiritual gift of
  faith deals with things “not yet come to pass,” else it would not be
  faith. It is not a vocal gift, as it makes you to know and not to
  speak. It is not discerning of spirits, as it has nothing to do with a
  supernatural spirit. It helps one, to look into the heart, mind, or
  nature of a man and to know his secrets and intentions. It has helped
  people find lost articles, but its main purpose is to find lost souls.
  
  BIBLE EXAMPLES
  
  While Peter was lying flat on his back on the house
  top, the Spirit of God told him three men were seeking him (Acts
  10:19). Had Peter gone to school one hundred years he could not have
  gained such knowledge, The all-knowing God gave part of His knowledge
  to Peter by the Spirit.
  
  The Spirit of God told Samuel that Saul's
  asses had already been found, and let him know all that was in Saul's
  heart (1 Sam. 9.19-20). A voice from God told Elijah that God had
  seven thousand who had not bowed their knees to Baal (1 Kings 19:18).
  A spiritual revelation!


And before that he wrote, in direct contrast to pentecostal pioneer Donald Gee:


  This gift has no mixture with the natural.


Now I only need to know if this view was shared by the other leaders during the same era.
