'Deceitful' in the Bible

A Prayer of David.Hear a just cause, O Lord, give heed to my cry;Give ear to my prayer, which is not from deceitful lips.

I do not sit with deceitful men,Nor will I go with pretenders.

For they do not speak peace,But they devise deceitful words against those who are quiet in the land.

Vindicate me, O God, and plead my case against an ungodly nation;O deliver me from the deceitful and unjust man!

You love all words that devour,O deceitful tongue.

For they have opened the wicked and deceitful mouth against me;They have spoken against me with a lying tongue.

Deliver my soul, O Lord, from lying lips,From a deceitful tongue.

What shall be given to you, and what more shall be done to you,You deceitful tongue?
