Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 5:35-43

“Those who were about the ruler of the synagogue, thought that Christ was one of the prophets, and for this reason they thought that they should beg of Him to come and pray over the damsel. But because she had already expired, they thought that He ought not to be asked to do so. Therefore it is said, While he yet spake, there came messengers to the ruler of the synagogue, which said, Thy daughter is dead; why troublest thou the Master any further? But the Lord Himself persuades the father to have confidence. For it goes on, As soon as Jesus heard the word which was spoken, he saith to the ruler of the synagogue, Be not afraid; only believe.”
