"Sing, O ye heavens; for the Lord hath done it: shout, ye lower parts of the earth: break forth into singing, ye mountains, O forest, and every tree therein: for the Lord hath redeemed Jacob, and glorified himself in Israel."
This is very cool. I can imagine walking through the forest, or in the mountains... and hearing the earth singing. :) The cliffs, the trees, the sea... all finding their voices because their God did something cool and amazing... so cool and amazing that the rocks shout for joy. Now, this is an amazing thing for rocks to do, as I'm sure you realize... rocks are very patient, and pretty dang quiet. You don't get into a conversation with a rock easily... so when a rock sings... when a whole mountain sings, in that incredible base voice of theirs... watch out. Something incredible is going on. :) Trees too... though not quite as patient as rocks, they are pretty dang close-mouthed. And, sincerely... who but God could be quite as amazing as to coax _song_ from that kind of resolved silence? So, then... all the rocks together and all the trees together... making up all the mountains and forests... and the heavens, and the lower parts of the earth... and they all form this choir, and what sound would be more pleasing than that? I can't think of any, at all... I want to hear it someday.
