'Treacherously' in the Bible

Indeed, none of those who [expectantly] wait for You will be ashamed;Those who turn away from what is right and deal treacherously without cause will be ashamed (humiliated, embarrassed).

You, O Lord God of hosts, the God of Israel,Arise to punish all the nations;Spare no one and do not be merciful to any who treacherously plot evil. Selah.

If I had said, “I will say this,” [and expressed my feelings],I would have betrayed the generation of Your children.

They turned back and acted unfaithfully like their fathers;They were twisted like a warped bow [that will not respond to the archer’s aim].
