The power to condemn others, by speaking evil of others, a voice of error. A right hand of falsehood.

Titus 3:2

All have sinned, and fall short of the glory of  GOD. Romans 3:23

Psalms 144:8

Those mouth speaketh vanity - Vain things; things not real and true; falsehood; lies. See the notes at Psa 24:4. The idea is, that what they said had no foundation in truth - no reality. Truth is solid and reliable; falsehood is unreliable and vain.

And their right hand is a right hand of falsehood - The meaning here seems to be that even under the solemnities of an oath, when they lifted up their hands to swear, when they solemnly appealed to God, there was no reliance to be placed on what they affirmed or promised. Oaths were taken by lifting up the right hand as toward God. See Gen 14:22; Exo 6:8 (Margin, and Hebrew); Deu 32:40.

Psalms 144:11

Rid me, and deliver me ... - See the notes at Psa 144:7-8. The language is here repeated. The prayer had been interrupted by the thought that the answer to it would lay the foundation for praise, and by an acknowledgment of entire dependence on God. The psalmist now, after repeating the prayer, suggests what would result from the answer to it, and dwells on the happy consequences which must follow; the bright scenes in his own reign, in the prosperity of the people, in the happiness of the nation, in domestic comforts, and in the abundance which the land would produce when these dangers should pass away, when people now engaged in the conflict of arms might return to the peaceful pursuits of life, when families would be safe in their dwellings, and when the earth cultivated in time of peace would again produce abundance, Psa144:12-14.

Albert Barnes puts these Psalms into perspective, however God is the counsel for all things. Men  who

counsel  with men, instead of God can miss the truth, and error in teaching, preaching, by teaching their

own thoughts instead of the oracles of God. Its oovious men think they are right in their own minds , and dismiss the truth of God`s word by misapplication, misunderstanding, and misinterpretation.

1Peter 4:11

 If any man speak, let him speak as the oracles of God; if any man minister, let him do it as of the ability which God giveth: that God in all things may be glorified through Jesus Christ, to whom be praise and dominion for ever and ever. Amen.
