Let the heavens rejoice, let the earth be glad; let them say among the nations, "The LORD reigns!" Let the sea resound, and all that is in it; let the fields be jubilant, and everything in them! Then the trees of the forest will sing, they will sing for joy before the LORD, for he comes to judge the earth.
1 Chronicles 16:31-33
If you shout a pleasant greeting to your neighbor too early in the morning, it will be counted as a curse! Pr 27:14
