" 'I will pour on the house of David and on the inhabitants of Jerusalem a spirit of grace and supplication, and they will look to me whom they pierced, and they shall mourn over him, as one wails over an only child, and they will grieve bitterly over him as [one] grieves bitterly over a firstborn.

Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.
