'Enough' in the Bible

Are there not enough unbalanced men about me, that you have let this person come and do such tricks before me? is such a man to come into my house?

So get up early in the morning along with the servants of your lord who have come with you. When you get up early in the morning, as soon as it is light enough to see, leave."

Then David and the people who [were] with him raised their voices and wept until there was not [enough] strength in them to weep.
