Geneisis 18:2 When he raised his eyes, then he looked and there three men were standing some distance from him. When he caught sight of them he began running to meet them from the entrance of the tent and proceeded to bow down to the earth. 3 Then he said: “Jehovah, if, now, I have found favor in your eyes, please do not pass by your servant. 4 Let a little water be taken, please, and YOU must have YOUR feet washed. Then recline under the tree. 5 And let me get a piece of bread, and refresh YOUR hearts. Following that, YOU can pass on, because that is why YOU have passed this way to YOUR servant.” At this they said: “All right. You may do just as you have spoken.”
Genesis 19:1 Now the two angels arrived at Sod´om by evening, 10 So the men thrust out their hands and brought Lot in to them, into the house, and they shut the door. 11 But they struck with blindness the men who were at the entrance of the house, from the least to the greatest, so that they were wearing themselves out trying to find the entrance. 12 Then the men said to Lot: “Do you have anyone else here? Son-in-law and your sons and your daughters and all who are yours in the city, bring out of the place! 17 as soon as they had brought them forth to the outskirts, he began to say: “Escape for your soul! Do not look behind you and do not stand still in all the District! Escape to the mountainous region for fear you may be swept away!”
18 Then Lot said to them: “Not that, please, Jehovah! 19 Please, now, your servant has found favor in your eyes so that you are magnifying your loving-kindness, which you have exercised with me to preserve my soul alive, but I—I am not able to escape to the mountainous region for fear calamity may keep close to me and I certainly die. 20 Please, now, this city is nearby to flee there and it is a small thing. May I, please, escape there—is it not a small thing?—and my soul will live on.” 21 So he (Jehovah) said to him: “Here I do show you consideration to this extent also, by my not overthrowing the city of which you have spoken. 22 Hurry! Escape there, because I am not able to do a thing until your arriving there!” That is why he called the name of the city Zo´ar.
23 The sun had gone forth over the land when Lot arrived at Zo´ar. 24 Then Jehovah made it rain sulphur and fire from Jehovah, from the heavens, upon Sod´om and upon Go·mor´rah.
What is my point with all of this? Jesus is God (John 20:28, Hebrews 1 and 2). The Holy Spirit is God (Acts 5:3-4). The Father is God (Ephesians 4:6).
In the OT, Jehovah is the name of God.
In the NT, Jesus makes his Father's name known without ever using it. How does Jesus do this? Look at his name. The name Jesus in Greek = Yehoshuah in Hebrew = YHWH + Salvation
