'Often' in the Bible

Whenever the unclean spirits saw Him, they fell down before Him and screamed out, “You are the Son of God!”

Because that he had been often bound with fetters and chains, and the chains had been plucked asunder by him, and the fetters broken in pieces: neither could any man tame him.

The spirit has often thrown him into fire and into water to destroy him. But if you are able to do anything, have pity on us and help us!"
