...then Jesus tells this story about the wicked tenants in the vineyard. Really, he’s invoking the prophet Isaiah. Everyone back then would have known the song of the vineyard which is today’s first reading. He’s turning it around on them. It’s like Jesus wanted to stick the knife as far into these learned scholars and powerful religious leaders as he could.
The landowner: God. The rotten tenants: The religious leaders and scholars who didn’t get what Jesus was all about. The vineyard: God’s people - Israel. The son: Jesus.
People were probably wondering how many ways can Jesus call these people “corrupt”? They are so crooked, Jesus says, that these wicked tenants, these scholars and leaders, will be destroyed when the landowner returns. (the whole thing here)
