Interesting article.
Not to be picky with the writer but I think the title Adonay and El Shadday should be Adonai and EL Shaddai. When I left the WT cult and began a real study of the bible (which took more than a year btw) I bought several bible translations along with a Tanakh (Jewish bible by Jerusalem translation society). And I was amazed just how many names (and titles) for God the bible contains especially in the OT. So for JW's to insist that Jehovah is the only acceptable name is totally ridiculous. Here is a another list, some not included in the above article.
Names for God in the Tanakh - hebrew Scriptures
EL: God ("mighty, strong, prominent") used 250 times in the OT See Gen. 7:1, 28:3, 35:11; Nu. 23:22; Josh. 3:10; 2 Sam. 22:31, 32; Neh. 1:5, 9:32; Isa. 9:6; Ezek. 10:5. El is linguistically equivalent to the Moslem "Allah," but the attributes of Allah in Islam are entirely different from those of the God of the Hebrews. ELAH is Aramaic, "god." Elah appears in the Hebrew Bible in Jer. 10:11 (which is in Aramaic, and is plural, "gods"). In Daniel (the Aramaic sections) Elah is used both of pagan gods, and of the true God, also plural. Elah is equivalent to the Hebrew Eloah which some think is dual; Elohim is three or more. The gods of the nations are called "elohim." The origin of Eloah is obscure. Elohim is the more common plural form of El. Eloah is used 41 times in Job between 3:4 and 40:2, but fewer than 15 times elsewhere in the OT.
ELOHIM: God (a plural noun, more than two, used with singular verbs); Elohim occurs 2,570 times in the OT, 32 times in Gen. 1. God as Creator, Preserver, Transcendent, Mighty and Strong. Eccl., Dan. Jonah use Elohim almost exclusively. See Gen. 17:7, 6:18, 9:15, 50:24; I Kings 8:23; Jer. 31:33; Isa. 40:1.
EL SHADDAI: God Almighty or "God All Sufficient." 48 times in the OT, 31 times in Job. First used in Gen. 17:1, 2. (Gen. 31:29, 49:24, 25; Prov. 3:27; Micah 2:1; Isa. 60:15, 16, 66:10-13; Ruth 1:20, 21) In Rev. 16:7, "Lord God the Almighty." The Septuagint uses Greek "ikanos" meaning "all-sufficient" or "self-sufficient." The idols of the heathen are called "sheddim."
ADONAI: Lord in our English Bibles (Capital letter 'L ', lower case, 'ord') (Adonai is plural, the sing. is "adon"). "Master'' or "Lord" 300 times in the OT always plural when referring to God, when sing. the reference is to a human lord. Used 215 times to refer to men. First use of Adonai, Gen. 15:2. (Ex. 4:10; Judges 6:15; 2 Sam. 7:18-20; Ps. 8, 114:7, 135:5, 141:8, 109:21-28). Heavy use in Isaiah (Adonai Jehovah). 200 times by Ezekiel. Ten times in Dan. 9.
JEHOVAH: LORDin our English Bibles (all capitals). Yahweh is the covenant name of God. Occurs 6823 times in the OT First use Gen. 2:4 (Jehovah Elohim). From the verb "to be", havah, similar to chavah (to live), "The Self-Existent One," "I AM WHO I AM" or 'I WILL BE WHO I WILL BE" as revealed to Moses at the burning bush, Ex.3. The name of God, too sacred to be uttered, abbreviated ( . . . . ) or written "YHWH" without vowel points. The tetragrammaton. Josh., Judges, Sam., and Kings use Jehovah almost exclusively. The love of God is conditioned upon His moral and spiritual attributes. (Dan. 9:14; Ps. 11:7; Lev. 19:2; Hab. 1:12). Note Deut. 6:4, 5 known to Jews as the Sh'ma uses both Jehovah and Elohim to indicate one God with a plurality of persons.
