"There is no speech nor language where their voice is not heard" (19:3). Do the heavens really speak?

The psalm says they do, in its own way: "Day after day they pour out speech, and night after night they display knowledge" (19:2), and "Their voice has gone out through all the earth, their words to the end of the world" (19:4). The verse between is short in Hebrew, and has no word for where. Word by word it is ein omer, no speech, ve'ein devarim, and no words, beli nishma qolam, not heard, their voice. Ein is, in Brown-Driver-Briggs's words, a "particle of negation", and beli an "adv. of negation". So the verse can be read as the WEB has it: wherever there is speech or language, their voice is heard. It can also be read as saying the heavens speak without speech or words, their voice not heard, and yet, the next verse says, it "has gone out through all the earth" (19:4). The Hebrew allows both readings. The psalm doesn't say which it means, and these notes don't choose.
