4 Who hath ascended up into heaven, or descended? who hath gathered the wind in his fists? who hath bound the waters in a garment? who hath established all the ends of the earth? what is his name, and what is his son’s name, if thou canst tell?
This is a clear reference to God with metaphorical imagery regarding the power and immensity of His divine nature. The answer to the three questions here; about the ability to move between heaven and earth at will, to control the elements, and to create and make sure every part of the earth, is definitely only one entity, the God of the Bible.
The Jew might say that the reference to God’s Son is a reference to Israel because of Exodus 4:22.
Exodus 4:22 And thou shalt say unto Pharaoh, Thus saith the LORD, Israel is my son, even my firstborn:
However, within the context of creating, sustaining, and controlling the prophetic answer is the Lord Jesus Christ.
John 1:18 No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
It is Christ by whom all things were made and by whom all things are sustained and held together.
John 1:3 All things were made by him; and without him was not any thing made that was made.
Colossians 1:16 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: 17 And he is before all things, and by him all things consist.
As man is composed of three distinct parts (1Thessalonians 5:23) God consists of God the Father which is the soul of the Godhead, directing His will and His sovereignty while the Holy Spirit is the active Spirit of God throughout existence. Christ is the body of the Godhead, so to speak, the visible image of God, or God the Son.
Colossians 1:15 Who is the image of the invisible God, the firstborn of every creature:
Hebrews 1:3 Who being the brightness of his glory, and the express image of his person,
And yet, is God himself, as well.
John 14:9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?
John 10:30 I and my Father are one.
John 5:18 Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God.
Philippians 2:6 Who, being in the form of God, thought it not robbery to be equal with God:
He has ascended into heaven and descended to earth.
John 3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
