This paper examines the concept of kingship in the book of Ben Sira by exploring both the adages regarding rulers and the Praise of the Ancestors. In the former, Ben Sira stresses God’s sovereignty over the Gentile ruler, and in the latter he assures peace through fidelity to the Aaronide priesthood, especially the lineage of Simeon. He accomplishes the latter by depicting the Aaronide priesthood with royal attributes, especially aspects of the Davidic covenant, and Simeon’s service at the temple as not only the embodiment of wisdom (Sir 24) and the cosmos (Sir 42) but as the culmination of all of Israel’s history.
