All we like sheep have gone astray. 

If we say that we have no sin, we deceive ourselves, and the truth is not in us. § There is none righteous, no, not one; there is none who understands… They have all turned aside; they have together become unprofitable.You were like sheep going astray, but have now returned to the Shepherd and Overseer of your souls. §  I have gone astray like a lost sheep; seek Your servant, for I do not forget Your commandments.He restores my soul; He leads me in the paths of righteousness for His name’s sake.My sheep hear My voice, and I know them, and they follow Me. . . . I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. • What man of you, having a hundred sheep, if he loses one of them, does not leave the ninety-nine in the wilderness, and go after the one which is lost until he finds it?
