Sirach 50:23LXX

21And the people in prayer besought the Lord the most High, until the worship of the Lord was perfected, and they had finished their office.

22Then coming down, he lifted up his hands over all the congregation of the children of Israel, to give glory to God with his lips, and to glory in his name:

23And he repeated his prayer, willing to shew the power of God.

24And now pray ye to the God of all, who hath done great things in all the earth, who hath increased our days from our mother’s womb, and hath done with us according to his mercy.

25May he grant us joyfulness of heart, and that there be peace in our days in Israel for ever:
