'Sheep' in the Bible

“What man among you, who has 100 sheep and loses one of them, does not leave the 99 in the open field and go after the lost one until he finds it?

and coming home, he calls his friends and neighbors together, saying to them, ‘Rejoice with me, because I have found my lost sheep!’

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