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](https://christianity.stackexchange.com/q/14069/1407) . How did **the pioneers of the [healing revival](http://en.wikipedia.org/wiki/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?
