Sirach 50:14

14 And finishing the service at the altar, that he might adorn the offering of the most high Almighty,

Sirach 50:14 In-Context

12 When he took the portions out of the priests' hands, he himself stood by the hearth of the altar, compassed about, as a young cedar in Libanus; and as palm trees compassed they him round about.
13 So were all the sons of Aaron in their glory, and the oblations of the Lord in their hands, before all the congregation of Israel.
14 And finishing the service at the altar, that he might adorn the offering of the most high Almighty,
15 He stretched out his hand to the cup, and poured of the blood of the grape, he poured out at the foot of the altar a sweetsmelling savour unto the most high King of all.
16 Then shouted the sons of Aaron, and sounded the silver trumpets, and made a great noise to be heard, for a remembrance before the most High.
