'Searched' in the Bible

The heart is a twisted thing, not to be searched out by man: who is able to have knowledge of it?

Thus saith the LORD; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD.

They shall cut down her forest, saith the LORD, though it cannot be searched; because they are more than the grasshoppers, and are innumerable.

I have had Esau searched out, uncovering his secret places, so that he may not keep himself covered: his seed is wasted and has come to an end, and there is no help from his neighbours.

In those days and at that time,' declares the LORD, "the iniquity of Israel will be searched for, but there will be none; and the sin of Judah, but none will be found, because I'll pardon those I leave as a remnant.'"
