'Deceitfully' in the Bible

He who is innocent of hands and pure of heart, who does not lift up his soul to falseness, and does not swear deceitfully.

He turned their heart to hate his people, to deal deceitfully against his servants.

All your commands [are] faithful. They persecute me deceitfully; help me!

who speak against you deceitfully. Your enemies take [your name] in vain.
