Zohar on Tehillim 86 – The Midnight Prayer
Tehillim 86:2
-"Shomrah nafshi ki chasid ani, hosha avdecha atah Elokai bote'ach eilecha" - (Guard my soul, for I am a chasid; save Your servant who trusts in You).
Rabbi Yehuda said: Let us examine the end of the pasuk, and then the entire pasuk. At the end of the pasuk it says: "who trusts in You" הבוטחח אליך, although it should have said "who trusts in You הבוטח בך.
What is the meaning of the words: "who trusts in You"?
He answers: This is King David's promise—not to sleep at midnight, as it is written: "At midnight I rise to give thanks to You." (Tehillim 119:62)
It should have said "I rose", rather than "I will rise" —but the meaning is that "I will rise" and unite with You—forever.
