'Foolish' in the Bible

I say again, let no one think me foolish. But if so, yet receive me as foolish, that I also may boast a little.

For you bear with the foolish gladly, being wise.

For if I would desire to boast, I will not be foolish; for I will speak the truth. But I refrain, so that no man may think more of me than that which he sees in me, or hears from me.

I have become foolish in boasting. You compelled me, for I ought to have been commended by you, for in nothing was I inferior to the very best apostles, though I am nothing.
