Luke 15:4-7 New American Standard Bible (NASB)

⁴ “What man among you, if he has a hundred sheep and has lost one of them, does not leave the other ninety-nine in the ^[a]open pasture and go after the one that is lost, until he finds it? ⁵ And when he has found it, he puts it on his shoulders, rejoicing. ⁶ And when he comes home, he calls together his friends and his neighbors, saying to them, ‘Rejoice with me, because I have found my sheep that was lost!’ ⁷ I tell you that in the same way, there will be more joy in heaven over one sinner who repents than over ninety-nine righteous people who have no need of repentance.

Matthew 18:12-14 New American Standard Bible (NASB)

Ninety-nine Plus One

¹² “What do you think? If any man has a hundred sheep, and one of them goes astray, will he not leave the ninety-nine on the mountains, and go and search for the one that is lost? ¹³ And if it turns out that he finds it, truly I say to you, he rejoices over it more than over the ninety-nine that have not gone astray. ¹⁴ So it is not the will ^[a]of your Father who is in heaven for one of these little ones to perish.
