Strong’s Hebrew Lexicon:

Father: אָב ʼâb, awb; a primitive word; father, in a literal and immediate, or figurative and remote application:—chief, (fore-) father(-less), × patrimony, principal. Compare names in ‘Abi-‘.

Heaven: שָׁמַיִם shâmayim, shaw-mah’-yim; dual of an unused singular שָׁמֶה shâmeh; from an unused root meaning to be lofty; the sky (as aloft; the dual perhaps alluding to the visible arch in which the clouds move, as well as to the higher ether where the celestial bodies revolve):—air, × astrologer, heaven(-s).

G-d: אֱלֹהִים ʼĕlôhîym, el-o-heem’; plural of H433; gods in the ordinary sense; but specifically used (in the plural thus, especially with the article) of the supreme God; occasionally applied by way of deference to magistrates; and sometimes as a superlative:—angels, × exceeding, God (gods) (-dess, -ly), × (very) great, judges, × mighty.

Angel: מֲלְאָךְ mălʼâk, mal-awk’; from an unused root meaning to despatch as a deputy; a messenger; specifically, of ‘God’ [‘Elohiym], i.e. an angel (also a prophet, priest or teacher):—ambassador, angel, king, messenger.

Significance of the Creator’s Name:

YHWH (YH): “Modern scholars generally agree that YHWH is derived from the Hebrew triconsonantal root היה (h-y-h), “to be, become, come to pass”,^[3] an archaic form of which is הוה (h-w-h),^[4] with a third person masculine y- prefix, equivalent to English “he”. They connect it to [eg.] Exodus 3:14 – [ETC..] where the divinity [‘Elohiym of Israel, YHWH] who spoke with Moses responds to a question about his name by declaring: אֶהְיֶה אֲשֶׁר אֶהְיֶה (Ehyeh asher ehyeh),“I am that I am” or “I will be what I will be”^[5](in Biblical Hebrew the form of the verb here is not associated with any particular English tense).^[6][7][8]“

THE NAME THAT ‘EXPRESSES’ (IS) THE WORD AND WORKS OF ISRAEL’S ‘ELOHIYM:

“I WILL BE WHAT I WILL BE”.
