'Foolish' in the Bible

I say again, let no man think me foolish; but if ye do , yet as foolish receive me, that I also may glory a little.

For ye bear with the foolish gladly, being wise yourselves .

For if I should desire to glory, I shall not be foolish; for I shall speak the truth: but I forbear, lest any man should account of me above that which he seeth me to be , or heareth from me.

I am become foolish: ye compelled me; for I ought to have been commended of you: for in nothing was I behind the very chiefest apostles, though I am nothing.
