Bede
Patristic
A.D. 673–735
“The soul of the laborer labors for itself, etc. It is evident, according to the letter, that man expelled from paradise exercises daily labor so that he may not lack. For he compelled his mouth, when he spoke with the serpent and touched the forbidden thing, to suffer long exile with labor and to eat bread by the sweat of his face. But also the teacher compels his mouth to labor, because he must practice the good things he says.”
