'Found' in the Bible

God forbid: yea, let God be found true, but every man a liar; as it is written, That thou mightest be justified in thy words, And mightest prevail when thou comest into judgment.

What then shall we say that Abraham, our forefather, hath found according to the flesh?

and the commandment, which was unto life, this I found to be unto death:

And Isaiah is very bold, and saith, I was found of them that sought me not; I became manifest unto them that asked not of me.
