Origen, on Josh 5:10

“And the children of Israel abode in Galgal, and they kept the phase on the fourteenth day of the month, at evening, in the plains of Jericho:”

“For not before circumcision were they able to celebrate a Passover; nor immediately after circumcision, before they were healed, were they able to eat the flesh of the lamb. But after they were healed it is said that "the sons of Israel celebrated the Passover on the fourteenth day of the month." You see, therefore, that no one unclean celebrates Passover, no one uncircumcised, but whoever has been cleansed and circumcised, just as the apostle also interprets, saying, "For indeed Christ our Passover has been sacrificed. Therefore, let us celebrate the feast day, not with the old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth."”
