'Refrain From' in the Bible

If a word were essayed to thee, wouldest thou be grieved? But who can refrain from speaking?

"Refrain from talking with me so that I may speak; then let come to me what may.

"But if I speak, my pain isn't assuaged; if I refrain from speaking, what do I have to lose?"

Nobles would refrain from speaking, covering their mouths with their hands.

“They hate me, they stand aloof from me,And do not refrain from spitting in my face.
