From those ancient manuscripts a poet made an observation that is universal.  It is a truth that even the most simple person can understand.  It resonates in our souls:

"The heavens declare the glory of God:  and the firmament sheweth his handiwork.  Day unto day uttereth speech and night unto night sheweth knowledge.  There is no speech  nor language where their voice is not heard."

My interpretation:  If you look up, look around and listen, you will see something and hear something that rings true.  Our universe is truly a miracle.  And all people everywhere see the same thing and hear in their own language.  God speaks to our hearts.
