'Seek the Lord' in the Bible

But afterward shall the children of Israel convert, and seek the LORD their God, and David their king: and in the latter days they shall worship the LORD, and his loving-kindness.

They shall come with their sheep and bullocks to seek the LORD, but they shall not find him, for he is gone from them.

that they might sow unto righteousness, and reap the fruits of well doing: that they might plow up their fresh land and seek the LORD, till he came, and learned them righteousness.
