Sirach 50:18-28

18 The singers also sang praises with their voices, with great variety of sounds was there made sweet melody.
19 And the people besought the Lord, the most High, by prayer before him that is merciful, till the solemnity of the Lord was ended, and they had finished his service.
20 Then he went down, and lifted up his hands over the whole congregation of the children of Israel, to give the blessing of the Lord with his lips, and to rejoice in his name.
21 And they bowed themselves down to worship the second time, that they might receive a blessing from the most High.
22 Now therefore bless ye the God of all, which only doeth wondrous things every where, which exalteth our days from the womb, and dealeth with us according to his mercy.
23 He grant us joyfulness of heart, and that peace may be in our days in Israel for ever:
24 That he would confirm his mercy with us, and deliver us at his time!
25 There be two manner of nations which my heart abhorreth, and the third is no nation:
26 They that sit upon the mountain of Samaria, and they that dwell among the Philistines, and that foolish people that dwell in Sichem.
27 Jesus the son of Sirach of Jerusalem hath written in this book the instruction of understanding and knowledge, who out of his heart poured forth wisdom.
28 Blessed is he that shall be exercised in these things; and he that layeth them up in his heart shall become wise.
