Matthew 14:10 recounts John the Baptist's beheading — John is a prime example of a prophet sent by God and killed, as the parable describes.

Matthew 23:30 quotes Pharisees claiming they would not have killed prophets — yet the parable shows the tenants doing exactly that, condemning them.

Matthew 23:37 explicitly says Jerusalem kills prophets and stones those sent — the parable dramatizes this same historical rejection of God's messengers.

Jeremiah 2:30 laments that God's prophets were devoured by the sword — the parable's repeated sending and killing of servants echoes this pattern.

Mark 12:5 is the parallel account of the same parable — it confirms the same pattern of beating and killing the servants.

Luke 13:34 echoes Jerusalem killing the prophets — directly paralleling the tenants' abuse of the sent servants.

Luke 6:23 connects the servants' mistreatment to how prophets were treated — the same pattern of rejecting God's messengers.
