'Sheep' in the Bible

“What man among you, if he has a hundred sheep and has lost one of them, does not leave the ninety-nine in the open pasture and go after the one which is lost until he finds it?

And when he comes home, he calls together his friends and his neighbors, saying to them, ‘Rejoice with me, for I have found my sheep which was lost!’

“Which of you, having a slave plowing or tending sheep, will say to him when he has come in from the field, ‘Come immediately and sit down to eat’?
