'Curse' in the Bible

They only plan to thrust [him] down from his high position; they are pleased [with] deception. With their mouths they bless, but {inwardly} they curse. Selah

Because he wore a curse as his robe, let it enter {his body} like water, and into his bones like oil.

Let them curse, but you bless. [When] they arise, let them be put to shame, that your servant may be glad.
