Galatians 5:9 Meaning

7Ye did run well; who did hinder you that ye should not obey the truth?

8This persuasion cometh not of him that calleth you.

9A little leaven leaveneth the whole lump.

10I have confidence in you through the Lord, that ye will be none otherwise minded: but he that troubleth you shall bear his judgment, whosoever he be.

11And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased.
