Is there a verse about "big" and "small" lies being the same in God's kingdom? I am looking for a certain verse or passage.

The one I'm looking for contains statements about there being no such thing as a "small" lie or "big" lie and that lies are all the same in God's kingdom.
This might be the idea you're going for:


  James 2:10-11 ESV For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it. For he who said, “You shall not commit adultery,” also said, “You shall not murder.” If you do not commit adultery but do commit murder, you have become a lawbreaker.


"...just one point..." being the key statement. If you tell a "small lie" but don't tell a "big" one, you are just as much a law breaker before God because your heart intended to deceive in either case.
