'Foolish' in the Bible

Again I say, let no one think me foolish; but if you do, receive me even as foolish, so that I also may boast a little.

For you, being so wise, tolerate the foolish gladly.

For if I do wish to boast I will not be foolish, for I will be speaking the truth; but I refrain from this, so that no one will credit me with more than he sees in me or hears from me.

I have become foolish; you yourselves compelled me. Actually I should have been commended by you, for in no respect was I inferior to the most eminent apostles, even though I am a nobody.
