Jeremiah 29:15

“They speak of us as claytowners, made out of dirt, brutish and carnal, because, say they, we refuse to receive the things of the spirit; but of course they themselves are citizens of Jerusalem and their mother is in heaven.” — editor's note: Pelusiotæ, men of Pelusium, supposed to be derived from πηλός, “clay.” See Jerome’s Comm. on Jer. xxix. 14–20.
