In John 10, who abandons the sheep and runs away when he sees the wolf coming?

Answer: The hired hand

Unlike the good shepherd who lays down his life, the hired hand runs away because he does not care for the sheep.

“The hired hand is not the shepherd, and the sheep are not his own. When he sees the wolf coming, he abandons the sheep and runs away. Then the wolf pounces on them and scatters the flock.”— John 10:12 (BSB)
