Kabbalah do Psalmów 19:3

"Day to day utters speech" (Ibid. 3) is an allusion to the sacred day that belongs to those supernal days of the King, that praise the friends. And they say to each other the same words that are written, "Day to day utters" that same "speech," thereby praising Him. The words "and night to night" refer to the levels that govern the night. They praise one another with the knowledge that each (receives) from its friends. And by this state of harmony and perfection, they become their friends and beloved ones.
