I just read the end of Job this morning. Heschel could be channeling God's speech from it here. I'm also reminded of Psalm 8:4:
what are human beingsor Psalm 19:
that you think about them;
what are human beings that you pay attention to them? (CEB)
Heaven is declaring God’s glory;Or. . . you get the idea. YHWH is truly marvelous and his ways beyond understanding. When we think of that, we can't help but stand—or kneel—in awe!
the sky is proclaiming his handiwork.
2 One day gushes the news to the next,
and one night informs another
what needs to be known.
3 Of course, there’s no speech, no words—
their voices can’t be heard—
4 but their soundk extends
throughout the world;
their words reach the ends
of the earth. (CEB)
