Augustine of Hippo, on John 8:1

“And Jesus went unto mount Olivet.”

“(de Con. Evang. lib. ii. c. 10) As if to signify that such persons were to be written in earth, not in heaven, where He told His disciples they should rejoice they were written. Or His bowing His head (to write on the ground), is an expression of humility; the writing on the ground signifying that His law was written on the earth which bore fruit, not on the barren stone, as before.”
