'Enough' in the Bible

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.

He said to them, “Come away by yourselves to a secluded place and rest a little while”—for there were many [people who were continually] coming and going, and they could not even find time to eat.

He came back a third time and said to them, “Are you still sleeping and resting? Enough [of that]! The hour has come. Look, the Son of Man is being betrayed into the hands of sinners.
