7 Purge out the old chametz (leavened bread), that you may be issa chadasha (new dough, batzek, deaf dough, having no indication of fermentation), as you are indeed like matzot (unleavened bread). More than that, our Korban Pesach has been sacrificed, Moshiach. [SHEMOT 12:3-6,21]
8 So let us celebrate Pesach, not with old chametz, nor with the chametz of kavvanah ra'ah (malice) and wickedness, but with matzot of kenut (sincerity) and emes. [SHEMOT 12:14,15; DEVARIM 16:3]
9 I wrote to you in the iggeret not to mix with those engaging in acts of zenut (fornication),
10 Not meaning to completely disassociate from the zannayim of the Olam Hazeh or those guilty of chamdanut (greed) and the ones practicing hona'ah (swindling) or those guilty of avodah zarah (idol worship), als (since) in that case you would have to exit the Olam Hazeh.
11 But, now I wrote to you not to mix with any "Ach b'Moshiach" who is a zannay (fornicator) or a kamtzan (miser) or an oved elilim (idolater) or a megadef (reviler) or a shikkor (drunkard) or a shoded (robber); with such a man do not sit at tish (table), do not share betzi'at halechem (breaking of bread).
12 For what is it to me to sit as a dayan in the Bet Din and then judge ones outside the kehillah? Will your Bet Din not judge the ones within [the kehillah]?
13 But the outsiders Hashem judges. UVI'ARTA HARA MIKKIR'BECHA "You must purge the evil from among you" [DEVARIM 17:7; 19:19; 22:21,24; 24:7]
