I always thought that Yahweh, which is the Hebrew word for Jehovah, was the name of God, the Father & Yeshua was the name of His Son Jesus who pre-existed with Him because John 17:5 says, "And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was."   However, your 1/23 post RE: Donna Danna: Jesus is Jehovah (fivedoves.com) states that Jehovah is Jesus which is news to me.  Then I just read another article at What is the name of God the Father? Does the Bible tells us God's name? (carm.org) which says YHWH is the name of the Triune God.  

Then according to the Hebrew interlinear Bible at gen1.pdf (scripture4all.org) it was Elohim, which is plural for Eloah meaning more than 1, who created the heaven & the earth (Genesis 1:1) and in all the verses from Genesis 1:1-31 Elohim is used instead of the word God that is in our KJV of the Bible.  In fact, in Genesis 1:26-27, Elohim says, "Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. So Elohim created man in his own image, in the image of God created he him; male and female created he them."

However, John 1:1-2 says, "In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made."

Col 1:15-17, "Who is the image of the invisible God, the firstborn of every creature: For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:"

Ephesians 3:9 says, "And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:"

So how is it possible that Elohim (God, the Father & the pre-existent Jesus) created everything according to Genesis 1, and just Jesus created everything in heaven and in earth according to Col.1:15-17 when God (the Father) who created all things by Jesus Christ in Ephesians 3:9???  Then if you go to the Hebrew interlinear Bible beginning in Genesis 2:4, it was Yahweh Elohim (plural) that created the heavens & the earth according to gen2.pdf (scripture4all.org)  So if Jehovah (Yahweh) who you say is Jesus created all things by Jesus Christ, why does it say, God, who created all things by Jesus Christ?  It doesn't say Jehovah or Yahweh as Jesus who created all things by Jesus Christ in Ephesians 3:9.
