When Jesus saw the vast crowd, his heart was moved with pity for them, for they were like sheep without a shepherd; and he began to teach them many things. Mark 6:34
“Jesus said to his disciples: “What is your opinion? If a man has a hundred sheep and one of them goes astray, will he not leave the ninety-nine in the hills and go in search of the stray?” Matthew 18:12
“What man among you having a hundred sheep and losing one of them would not leave the ninety-nine in the desert and go after the lost one until he finds it?
Jesus appointed seventy-two other disciples whom he sent ahead of him in pairs to every town and place he intended to visit.
