ἐκ στόματος νηπίων καὶ θηλαζόντων κατηρτίσω αἶνον ἕνεκα τῶν ἐχθρῶν σου, τοῦ καταλῦσαι ἐχθρὸν καὶ ἐκδικητήν.

From the mouths of children and infants You have ordained praise (note: Literally You have ordained strength; LXX You have prepared praise; cited in Matthew 21:16) on account of Your adversaries, to silence the enemy and avenger.
