1 Corinthians 5:6

Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?

Your boasting is not good. Don't you know that a little yeast leavens the whole batch of dough?

Οὐ καλὸν τὸ καύχημα ὑμῶν. Οὐκ οἴδατε ὅτι μικρὰ ζύμη ὅλον τὸ φύραμα ζυμοῖ;

Oy kalon to kaychēma ymōn. Oyk oidate oti mikra zymē olon to phyrama zymoi;
