“When the shepherd
Has found it,
He lays it
On his shoulders,
καὶ εὑρὼν ἐπιτίθησιν ἐπὶ τοὺς ὤμους αὐτοῦ χαίρων,
Luke had Jesus continue his story or parable. When this shepherd found the lost sheep (καὶ εὑρὼν), he would lay it on his shoulders (ἐπιτίθησιν ἐπὶ τοὺς ὤμους αὐτοῦ), rejoicing (χαίρων). This parable of the lost sheep can also be found in Matthew, chapter 18:13, with some minor changes, indicating a Q source. Jesus then had a solemn pronouncement (ἀμὴν λέγω ὑμῖν). If this shepherd had found his one lost sheep (καὶ ἐὰν γένηται εὑρεῖν αὐτό), would he rejoice over that more than over the 99 sheep that had never wandered away (ὅτι χαίρει ἐπ’ αὐτῷ μᾶλλον ἢ ἐπὶ τοῖς ἐνενήκοντα ἐννέα τοῖς μὴ πεπλανημένοις)? Every single sheep was precious in the sight of this good shepherd. Do you think that everyone is precious in the sight of God?
