 They're going to mourn for him like one mourns for an only son and they'll weep bitterly over him like they weep bitterly over a firstborn. There's going to be a massive turning to Israel. Notice the components of this repentance of Israel here. It's going to be intense. It's going to be like mourning for an only son. It's going to be for their past rejection of Jesus. They're going to mourn over the one that they pierced. It's going to be national. The Jews nationally will turn as a group and it's going to be future.
