The work of Simon "the Just", the high priest, son of Onias, in the temple and the people gathered around him worshiping God. It is recorded in Sirach 50:5-21:
How glorious [Simon, the high priest] was when the people gathered round him as he came out of the inner sanctuary [from behind the veil]!What is it to do the work of God?
Like the morning star among the clouds,
like the moon when it is full;
like the sun shining upon the temple of the Most High,
and like the rainbow gleaming in glorious clouds;
like roses in the days of the first fruits,
like lilies by a spring of water,
like a green shoot on Lebanon on a summer day;
like fire and incense in the censer,
like a vessel of hammered gold adorned with all kinds of precious stones;
like an olive tree putting forth its fruit,
and like a cypress towering in the clouds.
When he put on his glorious robe and clothed himself with superb perfection and went up to the holy altar, he made the court of the sanctuary glorious. And when he received the portions from the hands of the priests, as he stood by the hearth of the altar with a garland of brethren around him, he was like a young cedar on Lebanon; and they surrounded him like the trunks of palm trees, all the sons of Aaron in their splendor with the Lord's offering in their hands, before the whole congregation of Israel.
Finishing the service at the altars, and arranging the offering to the Most High, the Almighty, he reached out his hand to the cup and poured a libation of the blood of the grape; he poured it out at the foot of the altar, a pleasing odor to the Most High, the King of all. Then the sons of Aaron shouted, they sounded the trumpets of hammered work, they made a great noise to be heard for remembrance before the Most High.
Then all the people together made haste and fell to the ground upon their faces to worship their Lord, the Almighty, God Most High. And the singers praised him with their voices in sweet and full-toned melody. And the people besought the Lord Most High in prayer before him who is merciful, till the order of worship of the Lord was ended; so they completed his service.
Then Simon came down, and lifted up his hands over the whole congregation of the sons of Israel, to pronounce the blessing of the Lord with his lips, and to glory in his name; and they bowed down in worship a second time, to receive the blessing from the Most High.
