Do not slaughter the paschal sacrifice while in possession of leaven

"You shall not offer the blood of My sacrifice with leavened bread; nor is the fat of My feast to remain overnight until morning.

Hebrew

יח לֹא-תִזְבַּח עַל-חָמֵץ, דַּם-זִבְחִי; וְלֹא-יָלִין חֵלֶב-חַגִּי, עַד-בֹּקֶר.

18 ὅταν γὰρ ἐκβάλω ἔθνη ἀπὸ προσώπου σου καὶ ἐμπλατύνω τὰ ὅριά σου, οὐ θύσεις ἐπὶ ζύμῃ αἷμα θυσιάσματός μου, οὐδὲ μὴ κοιμηθῇ στέαρ τῆς ἑορτῆς μου ἕως πρωί.
