"And when the LORD saw that he turned aside to see, God called unto him out of the midst of the bush, and said, Moses, Moses. And he said here am I."
The word "Lord" is translated from the Tetragrammaton YHWH, (Tetragrammaton means "four letter word"). YHWH is where modern translations get the word "Jehova". Most scholars seem to think this is an almalgamation of the consonants that make up the word Yaweh and the vowels that make up the word Adonai. The exact annunciation remains uncertain. Either way the name Jehovah has become an accepted annunciation for the Tetragrammaton, YHWH. The Tetragrammaton appears some 6828 times in the Masoretic text. The name Jehova means "self existent" and "eternal".
Hebrews 11:6 declares, "without faith it is impossible to please Him, for he that comes to God must believe that he is." Not only believe His "existence" but also that He is eternal. YHWH is thought be third person imperfect tense of the VERB "to be". That He was, and is, and is to come. That he not only exist but that He is timeless. That He always is in a state of "is" wether past or future. He not only knows a beginning from and end because he has seen it, but he exist in it. When we are in the spirit, our spirit man begins to tap into the timelessness of Christ. I'll have more to say on this subject in the future, but for now ruminate over this and "think on these things.
God bless and happy hunting.
