Isa. lxiii. 11; (R.V.), Where is He that brought them up out of the sea with the shepherds (Marg. shepherd) of His flock?  Cyril’s reading, ἐκ τῆς γῆς instead of ἐκ τῆς θαλάσσης is found in the Alexandrine ms. of the Septuagint.  Athanasius (Ad Serapion, Ep. i. 12) has the same reading and interpretation as Cyril.  By “the shepherds” are probably meant Moses and Aaron:  cf. Ps. lxxvii. 20:  Who leddest Thy people like sheep by the hand of Moses and Aaron. Heb. xiii. 20:  Now the God of peace, that brought again from the dead our Lord Jesus, that great Shepherd of the sheep, &c.  The word “great” is added by the Author of the Epistle to the Hebrews not by Isaiah.
