'Seek the Lord' in the Bible

Afterward shall the children of Israel return, and seek the LORD their God, and David their king; and shall fear the LORD and his goodness in the latter days.

They shall go with their flocks and with their herds to seek the LORD; but they shall not find him; he hath withdrawn himself from them.

Sow to yourselves in righteousness, reap in mercy; break up your fallow ground: for it is time to seek the LORD, till he come and rain righteousness upon you.
