Jesus told this parable after he'd told another one with a similar message about a shepherd who cares for 100 sheep and loses one. He searches for the one until he finds it and then rejoices. Jesus told these two parables in response to the Scribes and Pharisees who criticized him for spending time among and eating with publicans and sinners.
“Or what woman, having ten silver coins, if she loses one coin, does not light a lamp, sweep the house, and search carefully until she finds it? And when she has found it, she calls her friends and neighbors together, saying, ‘Rejoice with me, for I have found the piece which I lost!’ Likewise, I say to you, there is joy in the presence of the angels of God over one sinner who repents.” Luke 15:8-10
