This oracle begins in verse 1 with a description of victory for Judah and Jerusalem, so that even the feeblest of peoples will be like the house of David. In the midst of the Lord's outpouring of compassion and supplication, the people will look on the one whom they have pierced and respond with great mourning. The image is reminiscent of the suffering servant of Isaiah 52:13-53:12 and is applied to Jesus in John 19:37.
10 And I will pour out a spirit of compassion and supplication on the house of David and the inhabitants of Jerusalem, so that, when they look on the one* whom they have pierced, they shall mourn for him, as one mourns for an only child, and weep bitterly over him, as one weeps over a firstborn.
