Matthew 23:37-38

Picture this: You are a parent sending your child to appeal to someone whom you love and know is misdirected, misguided, misinformed, in anxiety and anguish because of sin and deception, and whose life you know could be turned around and be glorious and wonderful for him. You send your child to appeal to him, and he kills him or her—when all you wanted to do is to help him out of the mess that he is in but could not see the condition in which he lives. "The one who kills the prophets and stones those who are sent to her!"

Matthew 23:37-39

Jesus is lamenting His own death in Jerusalem, coming up very soon. He is also lamenting the destruction of Jerusalem in 70 AD coming up soon also, and He foreshadows the time of Jacob's troubles, as well coming up soon. The repeated word Jerusalem, Jerusalem, cries of personal anguish, much like the repeated Martha, Martha in Luke 10:41. God's love for us has always been there, as ours should be for these little children.
