Luke 10:21

In that hour Jesus rejoiced in spirit (Spiritu Sancto, Vulgate), because the Holy Spirit had, according to His promise, granted the disciples, though weak and unlearned men, the power of working wonders, and had thus led others to believe in Christ and to glorify God.

And hast revealed them unto babes, i.e. that thou hast revealed to my humble and unlearned disciples the truth, so that they might acknowledge Thee, the one true God, and Me whom Thou hast sent, and might be predestinated to eternal life; and that many others also, whom they have healed of their diseases, and from whom they have cast out devils, might be brought to the knowledge of God, and believe to the salvation of their soul.
