'Falsehood' in the Bible

Relent, let there be no falsehood; reconsider, for my righteousness is intact!

Is there any falsehood on my lips? Can my mouth not discern evil things?

“For He recognizes and knows false and worthless men,And He sees wickedness, will He not consider it?

And yet, ye are forgers of falsehood, Physicians of nought -- all of you,

How then comfort ye me in vain, seeing in your answers there remaineth falsehood?

If I have walked in falsehoodor my foot has rushed to deceit,

For truly my words shall be no falsehood: one perfect in knowledge is with thee.
