“And when he was come nigh, even now at the descent of the mount of Olives, the whole multitude of the disciples began to rejoice and praise God with a loud voice for all the mighty works that they had seen;”
Luke 19:37 — Greek Interlinear
Church Fathers on Luke 19:37

They beheld indeed many of our Lord’s miracles, but marveled most at the resurrection of Lazarus. For as John says, For this cause the people also met him, for that they heard that he had done this miracle. For it must be observed that this was not the first time of our Lord’s coming to Jerusalem, but He came often before, as John relates.
