Among the awesome readings for Shavuot are passages such as Acts 2 which, when examined in context are absolutely mind-blowing:
Acts 2: 21. And it will be (that) all who call (on) the name of Master YHWH will be saved.
Acts 2: 32. This Y'shua Elohim raised, and we (are) all of his witnesses. 33. And this is he who is exalted at the right hand of Elohim, and received the promise from the Father concerning the Ruach haKodesh. And he has poured out this gift, which behold you see and you hear. 34. For it was not (that) Dawid did ascend into Heaven, because he said, Master YHWH said to my Master, sit (yourself) at my right hand. 35. Until I place your enemies (as) a footstool for your feet.  36. Truly, therefore, let all the house of Israel know that Elohim has made this Y'shua the Mashiyach whom you executed on a stake both Master YHWH and Mashiyach." 37. And when they heard these things they were touched in their hearts, and they said to Shimon and to the rest of the Shlichim, "What should we do, our brothers?" 38. Shimon said to them, "Repent and be immersed each of you in the name of Master YHWH-Y'shua for the forgiveness of sins, that you may receive the gift of the Ruach haKodesh.
 Psalm 110:1.
 "Has made" meaning from Y'shua's birth; one of the clearest statements in the NT that Y'shua had occurrences of human and divine natures co-existing within him. The human side's total obedience to YHWH contributed to Y'shua qualifying as haMashiyach; the fact that the Ruach haKodesh (another name for YHWH), dwelled inside Y'shua, also establishes Y'shua as the image of YHWH.
 Shimon was preaching from the steps of the Temple in Jerusalem. Just below him were hundreds of mikveh (immersion) baths. Both the steps he spoke from and the baths are visible today outside the Western Wall. In Peter's day baptism wasn't an act of conversion from one religion to another, but an act of purification from sin. A person repented of their sin, prayed, and then entered into the waters of the mikveh to symbolize atonement.
 MarYah and Y'shua appear next to one another! Therefore, Keefa is saying that the divine part of Y'shua and YHWH are one and the same; he is referring to Him in both ways.
Further explanation: Within Y'shua the man is an occurrence of the One Divine Nature of YHWH, also known as the Ruach haKodesh. This is the literal meaning of the fullness of YHWH dwelling inside Mashiyach, and in accordance with Tanakh prophecy (Isaiah 53:1, Zechariah 12:10). The divine and human natures exist separately yet side-by-side within Y'shua. When it says He "sits at the right hand of His Father" it doesn't necessarily mean "sit" as in a separate chair. YHWH, who is Spirit, doesn't "sit." To be at the right hand (side) was to be on the side of power and favor in Hebraic thought, especially with respect to YHWH.
