Isa 42:5 Thus saith God Jehovah, he that created the heavens, and stretched them forth; he that spread abroad the earth and that which cometh out of it; he that giveth breath unto the people upon it, and spirit to them that walk therein:
Isa 42:6 I, Jehovah, have called thee in righteousness, and will hold thy hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles;
Isa 42:7 to open the blind eyes, to bring out the prisoners from the dungeon, and them that sit in darkness out of the prison-house.
Isa 42:8 I am Jehovah, that is my name; and my glory will I not give to another, neither my praise unto graven images.
Isa 42:9 Behold, the former things are come to pass, and new things do I declare; before they spring forth I tell you of them.
Compare to NT passages, still using the ASV
Colossians chapter 1
12giving thanks unto the Father, who made us meet to be partakers of the inheritance of the saints in light;
13who delivered us out of the power of darkness, and translated us into the kingdom of the Son of his love; 14in whom we have our redemption, the forgiveness of our sins:
15who is the image of the invisible God, the firstborn of all creation; 16for in him were all things created, in the heavens and upon the earth, things visible and things invisible, whether thrones or dominions or principalities or powers; all things have been created through him, and unto him; 17and he is before all things, and in him all things consist.
John chapter one
1In the beginning was the Word, and the Word was with God, and the Word was God. 2The same was in the beginning with God. 3All things were made through him; and without him was not anything made that hath been made.
Hebrews chapter 1
1God, having of old time spoken unto the fathers in the prophets by divers portions and in divers manners, 2hath at the end of these days spoken unto us in his'son, whom he appointed heir of all things, through whom also he made the worlds; 3who being the effulgence of his glory, and the very image of his substance, and upholding all things by the word of his power, when he had made purification of sins, sat down on the right hand of the Majesty on high; 4having become by so much better than the angels, as he hath inherited a more excellent name than they.
5For unto which of the angels said he at any time, Thou art my Son, This day have I begotten thee? and again, I will be to him a Father, And he shall be to me a Son?
6And when he again bringeth in the firstborn into the world he saith, And let all the angels of God worship him.
7And of the angels he saith, Who maketh his angels winds, And his ministers a flame a fire:
8but of the Son he saith, Thy throne, O God, is for ever and ever; And the sceptre of uprightness is the sceptre of thy kingdom.
9Thou hast loved righteousness, and hated iniquity; Therefore God, thy God, hath anointed thee With the oil of gladness above thy fellows.
10And, Thou, Lord, in the beginning didst lay the foundation of the earth, And the heavens are the works of thy hands:
11They shall perish; but thou continuest: And they all shall wax old as doth a garment;
12And as a mantle shalt thou roll them up, As a garment, and they shall be changed: But thou art the same, And thy years shall not fail.
13But of which of the angels hath he said at any time, Sit thou on my right hand, Till I make thine enemies the footstool of thy feet?
14Are they not all ministering spirits, sent forth to do service for the sake of them that shall inherit salvation?
Revelation chapter 22
12Behold, I come quickly; and my reward is with me, to render to each man according as his work is. 13 I am the Alpha and the Omega, the first and the last, the beginning and the end.
14Blessed are they that wash their robes, that they may have the right to come to the tree of life, and may enter in by the gates into the city. 15Without are the dogs, and the sorcerers, and the fornicators, and the murderers, and the idolaters, and every one that loveth and maketh a lie.
16 I Jesus have sent mine angel to testify unto you these things for the churches. I am the root and the offspring of David, the bright, the morning star.
Don't worry over much about "Jehovah" because it's "Jesus" you will have to give answer to, since he created it all.
