1 Corinthians 1:29

They that trust in their wealth, and boast themselves in the multitude of their riches;

Shall the axe boast itself against him that heweth therewith? or shall the saw magnify itself against him that shaketh it? as if the rod should shake itself against them that lift it up, or as if the staff should lift up itself, as if it were no wood.

Thus saith the LORD, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches:

Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.

For if Abraham were justified by works, he hath whereof to glory; but not before God.

I have therefore whereof I may glory through Jesus Christ in those things which pertain to God.

That, according as it is written, He that glorieth, let him glory in the Lord.

For who maketh thee to differ from another? and what hast thou that thou didst not receive? now if thou didst receive it, why dost thou glory, as if thou hadst not received it?

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