Circumcision in the Old Testament is where one becomes one of God’s people. Old Testament describes circumcision as a form of purification in God’s eyes. Those uncircumcised are described as repulsive to God.
As Philip pointed out, Isaiah certianly recognized the need for Jesus, the “arm of the Lord” or “Right Hand” of God, to save him from his sins. King David, though he does not know the name “Jesus” certianly recognized the need for salvation through God’s “Right Hand” which is Jesus. The psalms are written by King David. David was guilty of adultery, coveting another’s wife, and murder. David died a thousand years before the time of Christ. Yet repentant David proclaims salvation through the Right Hand of God the Father. It is by the blood of Jesus, the Right Hand of the Father, through which repentant sinner David is brought to eternal salvation.
NAB MAT 8:17
(Isaiah is speaking.) “It was our infirmities he bore, our sufferings he endured.” NAB ISA 53:4
(Isaiah to the Israelites.)
Who would believe what we have heard? To whom has the arm of the Lord been revealed? He grew up like a sapling before him, like a shoot from the parched earth; There was in him no stately bearing to make us look at him, nor appearance that would attract us to him. He was spurned and avoided by men, a man of suffering, accustomed to infirmity, One of those from whom men hide their faces, spurned, and we held him in no esteem. Yet it was our infirmities that he bore, our sufferings that he endured, While we thought of him as stricken, as one smitten by God and afflicted. But he was pierced for our offenses, crushed for our sins, Upon him was the chastisement that makes us whole, by his stripes we were healed. We had all gone astray like sheep, each following his own way; But the LORD laid upon him the guilt of us all.
NAB MAT 26:64
Jesus answered: “It is you who say it. But I tell you this: Soon you will see the Son of Man seated at the right hand of the Power and coming on the clouds of heaven.” NAB PSA 80:18
May your help be with the man of your right hand, with the son of man whom you yourself made strong.
NAB PSA 118:15
The joyful shout of victory in the tents of the just: "The right hand of the LORD has struck with power: The right hand of the LORD is exalted; the right hand of the LORD has struck with power." I shall not die, but live, and declare the works of the LORD. Though the LORD has indeed chastised me, yet he has not delivered me to death. Open to me the gates of justice; I will enter them and give thanks to the LORD. This gate is the LORD’s; the just shall enter it. I will give thanks to you, for you have answered me and have been my savior. The stone which the builders rejected has become the cornerstone. By the LORD has this been done; it is wonderful in our eyes. This is the day the LORD has made; let us be glad and rejoice in it. O LORD, grant salvation! O LORD, grant prosperity! (MAT 21:42)
NAB PSA 98:1
Sing to the Lord a new song, for he has done wondrous deeds; His right hand has won victory for him, his holy arm. The LORD has made his salvation known: in the sight of the nations he has revealed his justice. He has remembered his kindness and his faithfulness toward the house of Israel. **All the ends of the earth have seen the salvation by our God.**NAB WIS 5:15
But the just live forever, and in the LORD is their recompense, and the thought of them is with the Most High. Therefore shall they receive the splendid crown, the beauteous diadem, from the hand of the LORD - For he shall shelter them with his right hand, and protect them with his arm.NAB PSA 77:16

But you, Israel, my servant, Jacob, whom I have chosen, offspring of Abraham my friend - You whom I have taken from the ends of the earth and summoned from its far-off places, You whom I have called my servant, whom I have chosen and will not cast off - Fear not, I am with you; be not dismayed; I am your God. I will strengthen you and help you, and uphold you with my right hand of justice.NIV PSA 108:6
Save us and help us with your right hand, that those you love may be delivered.
