G1571–ἐκκαθαίρω–ekkathairō

Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place.

ἐκκαθάρατε ekkatharate “do cleanse out”

If anyone therefore purges himself from these, he will be a vessel for honor, sanctified, and suitable for the master's use, prepared for every good work.

ἐκκαθάρῃ ekkatharē “shall cleanse”
