Yehezkiel 44:11

The Levitical Priests

44:15 “‘But the Levitical priests, the descendants of Zadok ¹  who kept the charge of my sanctuary when the people of Israel went astray from me, will approach me to minister to me; they will stand before me to offer me the fat and the blood, declares the sovereign Lord.

[44:15]  ¹ sn Zadok was a descendant of Aaron through Eleazar (1 Chr 6:50-53), who served as a priest during David’s reign (2 Sam 8:17).
