<p>5:8 <em>Therefore let us keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the bread of sincerity and truth which has no yeast- </em>Paul's selfless relationship with Corinth was inspired by that of Moses with Israel. This is echoing Moses' command to keep the Passover feast without leaven, putting Moses' words in his own mouth (Ex. 12:15; Dt. 16:3). Paul saw himself as Moses in trying to save a generally unresponsive and ungrateful Israel.</p><p>In Dt. 16:3 the unleavened bread is called the &quot;bread of affliction&quot;, whilst in 1 Cor. 5:8 it is called the &quot;unleavened bread of sincerity and Truth&quot;, as if being sincere and true and not having malice and bitterness in our hearts is a result of much mental affliction and exercising of the mind. So to keep the feast we have to search our houses, our lives, for anything like leaven- anything that puffs us up, that distorts us from the true smallness and humility we should have, that corrupts our sincerity. By nature we have so much pride in us, so much that puffs us up. We should always find some leaven in us every time we examine ourselves. The Jews used to search their houses with candles, looking for any sign of leaven. So we too must look into every corner of our lives with the candle of the word. Similarly before the great Passovers of Hezekiah and Josiah there was a searching for idols which were then thrown down. Note how Paul calls on the Corinthians to keep the feast &ldquo;with the unleavened bread of sincerity and truth,&rdquo; which he contrasts with &ldquo;malice and evil&rdquo; (1 Cor. 5:8). Truth is set up against evil- not against wrong interpretations of Bible passages.</p>
