'Seek the Lord' in the Bible

Afterward the children of Israel shall return, and seek the LORD their God, and David their king, and shall come with trembling to the LORD and to his blessings in the last days.

They will go with their flocks and with their herds to seek the LORD; but they won't find him. He has withdrawn himself from them.

Sow to yourselves in righteousness, reap according to kindness. Break up your fallow ground; for it is time to seek the LORD, until he comes and rains righteousness on you.
