יהו"ה-- היה הווה ויהיה

Chazal say (source?) the meaning of יהו"ה being היה הווה ויהיה -- presumably from the 3 vowelizations of שב"א, חול"ם, וקמ"ץ.  The beginning שב"א for future e.g. יהי אור, the חול"ם used for present e.g הווה, עושה  ; and קמץ for past e.g. היה, נהיה.

Problem is though, Chazal should state the order opposite:  יהיה הווה והיה as per the vowelization...

לענ"ד from the perspective of Mankind, Creation's processes are leading up towards ultimate Existential completion, hence היה הווה ויהיה but from the perspective of Primal Existence/ יהו"ה, an existentialist perspective, the ultimate future final result of what remains is your point of origin, how could you begin from things which "are-not"?; what remains are the particular processes by which Existence shall manifest itself but one way or another, those existential Truths will manifest. Hence from an existentialist perspective the effect exists before the causes that bring it about --- רווח והצלה יעמוד ליהודים ממקום אחר ואת ובית אביך תאבדו. As R' Matis Weinberg explained in Frameworks Pr' Hukat.

.....In the same way then that mathematical truths precede and are pre-determined even before the selection of the particular causal data that bring them about, as for example x + y = 20. The result will be 20, no matter what 'x' you choose.

It is interesting then, following this line of thinking, that the שם of צבאות follows a different order, namely: Future, Past, Present... וצע"ע
