It appears as though the writer of Hebrews is including verses 10-12 as additional statements that Yahweh has made to His Son. But if we look a little deeper we will find several discrepancies. Verses 10-12 are direct quotes from
Ps.102:25-27. They are not a quote from the Hebrew Text, however, but from the Septuagint (LXX). The Hebrew Text does not have "Lord" in it. Therefore, to say that "Lord" in
Heb.1:10 proves that Yeshua is YHWH is unscriptural. The LXX has "Kurie" in
Ps.102:25. The LXX also omits "O my el" in verse 24.
Here is what the writer of the book of Hebrews, says as inspired by the Holy Spirit.
8 But to the Son
He says: “Your throne,
O God, is forever and ever;
A scepter of righteousness
is the scepter of Your kingdom.
9 You have loved righteousness and hated lawlessness;
Therefore God, Your God, has anointed You
With the oil of gladness more than Your companions.”
10 And:
“You, Lord, in the beginning laid the foundation of the earth,
And the heavens are the work of Your hands. Hebrews 1:8-10
This lines up with what Paul says -
16 For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. 17 And He is before all things, and in Him all things consist.
Colossians 1:16-17
and again
looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ, Titus 2:13
and again
And without controversy great is the mystery of godliness: God was manifested in the flesh... 1 Timothy 3:16
John says it this way -
In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things were made through Him, and without Him nothing was made that was made. John 1:1-2
and again
12 “And behold, I am coming quickly, and My reward is with Me, to give to every one according to his work. 13 I am the Alpha and the Omega, the Beginning and the End, the First and the Last.” Revelation 22:12
And Peter -
10 But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up.11 Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness, 12 looking for and hastening the coming of the day of God, because of which the heavens will be dissolved, being on fire, and the elements will melt with fervent heat?
2 Peter 3:10-12
Peter plainly writes of Jesus, as the Lord [YHWH] who is coming as a thief in the night, as he quotes from Joel.
Jesus is the Lord God, who is coming with His saints, like a thief in the night.
He created all things, and laid the foundation of the earth, and stretched out the heaven, as they are the work of His hands.
8 But to the Son
He says: “Your throne, O God,
is forever and ever;
A scepter of righteousness
is the scepter of Your kingdom.
9 You have loved righteousness and hated lawlessness;
Therefore God, Your God, has anointed You
With the oil of gladness more than Your companions.”
10 And: “You, Lord, in the beginning laid the foundation of the earth,
And the heavens are the work of Your hands. Hebrews 1:8-10 NKJV
8 But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom.
9 Thou hast loved righteousness, and hated iniquity; therefore God, even thy God, hath anointed thee with the oil of gladness above thy fellows. 10 And, Thou, Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands:
Hebrews 1:8-10 KJV
8 But of the Son
He says, Your throne, O God, is forever and ever,
And the righteous scepter is the scepter of “His kingdom.
9 You have loved righteousness and hated lawlessness; Therefore God, Your God, has anointed You
With the oil of gladness above Your companions.”
10 And, You, Lord, in the beginning laid the foundation of the earth,
And the heavens are the works of Your hands; Hebrews 1:8-10 NASB
8 and unto the Son: `Thy throne, O God, [is] to the age of the age; a scepter of righteousness [is] the scepter of thy reign;
9 thou didst love righteousness, and didst hate lawlessness; because of this did He anoint thee -- God, thy God -- with oil of gladness above thy partners;' 10 and, `Thou, at the beginning, Lord, the earth didst found, and a work of thy hands are the heavens;
Hebrews 1:8-10 YLT
But about the Son he says, “Your throne, O God, will last for ever and ever;
You have loved righteousness and hated wickedness; therefore God, your God, has set you above your companions by anointing you with the oil of joy.” He also says, “In the beginning, Lord, you laid the foundations of the earth, and the heavens are the work of your hands.Hebrews 1:8-10 NIV
8 but to the Son, he says, “Your throne, O God, will last forever and ever; you rule your Kingdom with a scepter of equity;
9 you have loved righteousness and hated wickedness. Therefore, O God, your God has anointed you with the oil of joy in preference to your companions”; 10 and, “In the beginning, Lord, you laid the foundations of the earth; heaven is the work of your hands.
