'Ninety nine' in the Bible

And Abram was ninety-nine years old, when Jehovah appeared to Abram, and said to him, I am the Almighty God: walk before my face, and be perfect.

And Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin.

12 "What do you think? If a man has one hundred sheep, and one of them goes astray, does he not leave the ninety-nine, go to the mountains, and seek that which has gone astray?

What think ye? if a man may have an hundred sheep, and there may go astray one of them, doth he not -- having left the ninety-nine, having gone on the mountains -- seek that which is gone astray?

and if it may come to pass that he doth find it, verily I say to you, that he doth rejoice over it more than over the ninety-nine that have not gone astray;

'What man of you having a hundred sheep, and having lost one out of them, doth not leave behind the ninety-nine in the wilderness, and go on after the lost one, till he may find it?

'I say to you, that so joy shall be in the heaven over one sinner reforming, rather than over ninety-nine righteous men, who have no need of reformation.
