5 ⁿIs such the fast that I choose,

and a day acceptable to the Lord?

Him Whom They Have Pierced

10 “And ^sI will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and ^tpleas for mercy, so that, ^uwhen they look on me, on him whom they have pierced, ^vthey shall mourn for him, ^was one mourns for an only child, and weep bitterly over him, as one weeps over a firstborn.
