Sirach chapter 50 describes a liturgical practice known as the Day of Atonement which occurred once a year where the high priest in full vestments and with many surrounding priests in the presence of a great assembly of worshipers would sacrifice the offerings with trumpet blasts and praise to God from the people culminating in the high priest saying the Holy Name over the people.
Sirach 50:20-24 Then coming down he (high priest) would raise his hands over the congregation of Israel. The blessing of the LORD would be upon his lips, the Name of the LORD would be his glory. Then again the people would lie prostrate to receive from him the blessing of the Most High. And now, bless the God of all, who has done wondrous things on earth; who fosters men’s growth from their mother’s womb, and fashions them according to His will! May He grant you joy of heart and may peace abide among you; may His goodness toward us endure in Israel as long as the heavens are above.
++If you can, read the last chapter of Sirach, chapter 51. It is beautiful -especially verses 13 to 30 which talk about seeking wisdom++ eg. verse 27: see for yourselves! I have labored only a little, but have found much.
Sirach 51:10-12 I called out: O LORD, You are my Father, You are my Champion and my Savior; Do not abandon me in time of trouble, in the midst of storms and dangers. I will ever praise Your Name and be constant in my prayers to You. Thereupon the LORD heard my voice, He listened to my appeal; He saved me from evil of every kind and preserved me in time of trouble. For this reason I thank Him and I praise Him; I bless the Name of the LORD.
