Mark 12:3-6
12:3 But those tenants seized his slave, beat him, and sent him away empty-handed.
12:4 So he sent another slave to them again. This one they struck on the head and treated outrageously.
12:5 He sent another, and that one they killed. This happened to many others, some of whom were beaten, others killed.
12:6 He had one left, his one dear son. Finally he sent him to them, saying, ‘They will respect my son.’
