Emunah 1

"For I know that Hashem is Great, and our Lord from all other gods". King David, peace be upon him, said: "For I know" — specifically I, for the greatness of the Blessed Creator is impossible to tell to someone else, and even to oneself it is impossible to tell from day to day, according to what dawns on him and sparkles for him that day. He cannot tell himself on another day the shining and the sparkling of the greatness of the Blessed One that he had yesterday. And therefore he said: "I know", specifically, for it impossible to tell at all. And he said that what is written after that, "Whatever Hashem pleased, he has done; in heaven and on earth" etc., is a completely different matter and completely distant from the praise, "For I know," for his intention in these words, "For I know" is impossible to tell at all, and it is very, very high, high beyond high, impossible for the mouth to tell; only "I know" specifically, as mentioned, and as written in the Zohar (Vol. 1, page 103): "Her husband is known at the gates (Proverbs 31:23)" — each person according to what he fits in his heart, as explained in a different place [See Likutei Moharan #73,#63].

Praise befits You in Zion, O God; vows are paid to You;
