Mark 12:7 But those husbandmen said among themselves, This is the heir; come, let us kill him, and the inheritance shall be ours.
But in this case the vine dressers spoke among themselves, Since this is the heir; come together, kill him, and the inheritance shall be ours.
Interesting and Hidden Aspects:
The words used for "say" in this verse and the previous verse are different in Greek. The word used when the landowner speaks (legô) has more of a sense of statement. The word used to describe the vine dressers (eipon) has more of a sense of discussion. The two words translated simply as "this" describing the heir have the sense of justifying something (hoti=since, houtos=that is why).
