'Searching' in the Bible

Why? Because they were not searching for it by faith, but by works. They came up against the stone which was in the way;

And Isaiah says without fear, Those who were not searching for me made discovery of me; and I was seen by those whose hearts were turned away from me.

Lord, they have put your prophets to death, and made waste your altars, and now I am the last, and they are searching for me to take away my life.

What then? That which Israel was searching for he did not get, but those of the selection got it and the rest were made hard.
