'Investigate' in the Bible

You search and keep on searching and examining the Scriptures because you think that in them you have eternal life; and yet it is those [very Scriptures] that testify about Me;

When Moses saw it, he was astonished at the sight; but as he went near to look more closely, the voice of the Lord came [to him, saying]:

So now you, along with the Council (Sanhedrin, Jewish High Court), notify the commander to bring Paul down to you, as if you were going to investigate his case more thoroughly. But we are ready to kill him before he comes near [the place].”

But [as for me personally] it matters very little to me that I may be judged by you or any human court [on this point]; in fact, I do not even judge myself.
