'Redeemed of the Lord' in the Bible

Let the redeemed of the LORD say so, whom he hath redeemed from the hand of the enemy;

And the redeemed of the LORD shall convert, and come to Zion with thanksgiving. Everlasting joy shall they have, pleasure and gladness shall be among them. And as for all sorrow and heaviness, it shall vanish away.

Therefore the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away.

And they shall call them, The holy people, The redeemed of the LORD: and thou shalt be called, Sought out, A city not forsaken.
