Neither shall there be leaven seen with thee in all thy quarters. Exodus 13:7
The fear of the LORD is to hate evil. — Abhor that which is evil. — Abstain from all appearance of evil. —Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled. If I regard iniquity in my heart, the Lord will not hear me.
Know ye not that a little leaven leaveneth the whole lump? 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: therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. — Let a man examine himself, and so let him eat of that bread, and drink of that cup.
Let every one that nameth the name of Christ depart from iniquity. — Such an high priest became us, who is holy, harmless, undefiled, separate from sinners. — In him is no sin.
