“Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us:”
King James Version (KJV)
5:7 Purge out therefore the old leaven - Both of sinners and of sin. That ye may be a new lump, as ye are unleavened - That is, that being unleavened ye may be a new lump, holy unto the Lord. For our passover is slain for us - The Jewish passover, about the time of which this epistle was wrote, #1Cor 5:11|, was only a type of this. What exquisite skill both here and everywhere conducts the zeal of the inspired writer! How surprising a transition is here, and yet how perfectly natural! The apostle, speaking of the incestuous criminal, slides into his darling topic, - crucified Saviour. Who would have expected it on such an occasion. Yet, when it is thus brought in, who does not see and admire both the propriety of the subject, and the delicacy of its introduction?
1Co 5:7 Purge out therefore the old leaven. Let the leaven of impurity be removed, by putting out the fornicator, that the church may be pure from the impure leaven, or influence. So, too, each one must cleanse his own heart. For even Christ our passover is sacrificed for us. At the passover, Jews were required to put all leaven from their houses (Ex 12:15). As we have a Paschal Lamb, slain for us, the church should cleanse out the leaven of sin.
