Blood

I will pour out on the house of David and on the inhabitants of Jerusalem a spirit of mercy and supplication, so that when they look on him whom they have pierced, they will mourn for him as one mourns for an only child, and they will grieve for him as one grieves over a firstborn.

Zechariah 12

It pleased God to make absolute fullness reside in him
and by means of him to reconcile everything in his person,
both on earth and in the heavens,
making peace through the blood of his cross.

Colossians
