Basil of Caesarea
Patristic
c. A.D. 330–379
“You have given a sign, the blood itself of a lamb without blemish, slain for the sin of the world. And Ezekiel says that a sign was given on the foreheads of the persons.”
From the early Church Fathers to now.
“And to the others he said in my hearing: Go ye after him through the city, and strike: let not your eyes spare, nor be ye moved with pity.”
“You have given a sign, the blood itself of a lamb without blemish, slain for the sin of the world. And Ezekiel says that a sign was given on the foreheads of the persons.”
“In Ezekiel the prophet, when the angel who had been sent had slain everyone and the slaughter had begun at the holy places, only those whom he had signed with the letter tau—that is, with the mark of the cross—remained unharmed.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
