'Searched' in the Bible

This is what the LORD says: "If the heavens could be measured above, or the foundations of the earth be searched out below, then I also would reject all the descendants of Israel because of everything they have done," declares the LORD.

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.'"
