“But they seized
They beat him.
They sent him away
καὶ λαβόντες αὐτὸν ἔδειραν καὶ ἀπέστειλαν κενόν.
This beating of the slave by the wicked tenants can be found somewhat similar in Matthew, chapter 21:35, and Luke, chapter 20:10, but there was only one slave here and in Luke, instead of the 3 different slaves, as in Matthew. Mark said that these tenant farmers seized this slave (καὶ λαβόντες αὐτὸν). They beat him (ἔδειραν). Then they sent him away empty-handed (καὶ ἀπέστειλαν κενόν). These tenant farmers were not very nice.
