1 Esdras 1:21-23
21 Yea, all the kings of Israel held not such a passover as Josias, and the priests, and the Levites, and the Jews, held with all Israel that were found dwelling at Jerusalem.
22 In the eighteenth year of the reign of Josias was this passover kept.
23 And the works or Josias were upright before his Lord with an heart full of godliness.
