Augustine of Hippo

..."He hath sent from heaven His mercy and His truth." For what purpose? "And hath drawn out my soul from the midst of the lions' whelps" [Psalm 57:4]. "Hath sent," he saith, "from heaven His mercy and His truth:" and Christ Himself saith, "I am Truth." There was sent therefore Truth, that it should draw out my soul hence from the midst of the lions' whelps: there was sent mercy. Christ Himself we find to be both mercy and truth; mercy in suffering with us, and truth in requiting us. ...Who are the lions' whelps? That lesser people, unto evil deceived, unto evil led away by the chiefs of the Jews: so that these are lions, those lions' whelps. All roared, all slew. For we are to hear even here the slaying of these very men, presently in the following verses of this Psalm. "And hath drawn out," he saith, "my soul from the midst of the lions' whelps." Why sayest thou, "And hath drawn out my soul"? For what hadst thou suffered, that thy soul should be drawn out? "I have slept troubled." Christ hath intimated His death. ...
