Lucas 15

4 What man of you, if he has meah kevasim (a hundred sheep) and has lost from them one, does not leave the tishim vteshah (ninety-nine) in the open pasture, and go for the one which has been lost until he finds it? 5 And when he has found it, he puts it on his shoulders with lev same’ach.*15:5 Ps 23; 119; Jer 31:10; Ezek 34:11-16 6 And when he returns to his bais, he calls together his chaverim and his shchenim (neighbors), saying to them, Make a simcha with me, because I have found my keves (sheep), the one that was lost! 7 I say to you that in the same way there will be more simcha in Shomayim over one choteh (sinner) who becomes a baal teshuva than over tishim vteshah tzaddikim who have no need of teshuva.
