Augustine (354-430) while commenting on Isaiah 43:
"What comes next? I will make a way in the wilderness. In which wilderness? That of the nations, of course, where there was no worship of the true God. I will make a way in the wilderness, and streams in the dry places. Nowhere among the nations were the prophets ever read, now their writings are flooding all the nations."
