Luke

For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.

For the Son of man is come to seek and to save that which was lost.

I will seek that which was lost, and bring again that which was driven away, and will bind up that which was broken, and will strengthen that which was sick: but I will destroy the fat and the strong; I will feed them with judgment.

How think ye? if a man have an hundred sheep, and one of them be gone astray, doth he not leave the ninety and nine, and goeth into the mountains, and seeketh that which is gone astray?

For thus saith the Lord God; Behold, I, even I, will both search my sheep, and seek them out.
