'Often' in the Bible

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

For he had often been bound with shackles [for the feet] and with chains, and he tore apart the chains and broke the shackles into pieces, and no one was strong enough to subdue and tame him.

The demon has often thrown him both into fire and into water, intending to kill him. But if You can do anything, take pity on us and help us!”
