1 Samuel 26:25

Blessed be thou, my son David Saul perceived that it was in vain to contend any longer against David, whom he saw God intended for great things. And so strong was his conviction now of this, as well as of his own sin and folly, that he could not forbear blessing him, foretelling his success, applauding him, and condemning himself, even in the hearing of his own soldiers. And this, it seems, was their last interview. After this they saw each other no more.
