In John 18:9, Jesus (or John) says:
That the saying might be fulfilled, which he spake, Of them which thou gavest me have I lost none.
However, I couldn't find what scriptures is being quoted here. I checked every verse in the Bible for the words loss/lose/lost and came up with nothing. (there were only 32 search hits).
So is this a quote of some scripture that is not in the Bible?
