Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 10:23-24

“Having said above, No one knoweth who the Father is but the Son, and to whomsoever the Son will reveal him; He pronounces a blessing upon His disciples, to whom the Father was revealed through Him. Hence it is said, And he turned him unto his disciples, and said, Blessed are the eyes, &c.”
