This is not the OT Covenant (although the cross was there).
The cross in the OT:
Isaiah 53
1 Corinthians 2:2 For I determined not to know any thing among you, save Jesus Christ, and him crucified.
The cross in the OT:
Genesis 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
Isaiah 53
5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.
7 He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
8 He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken.
9 And he made his grave with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth.
10 Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.
11 He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.
12 Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors.

Psalm 22
15 My strength is dried up like a potsherd; and my tongue cleaveth to my jaws; and thou hast brought me into the dust of death.
16 For dogs have compassed me: the assembly of the wicked have inclosed me: they pierced my hands and my feet.
17 I may tell all my bones: they look and stare upon me.
18 They part my garments among them, and cast lots upon my vesture.

The OT altar of wood upon which the blood of the lamb was poured out was made of acacia wood overlayed with brass.
Jesus Christ was crucified upon Acacia wood because it is the tree found in Palestine with thorns. They stripped them off the cross-beam in preparation for His crucifixion and made the crown for the King of kings with them.
The eternal gospel had the marks of the cross from the beginning.
The cross of Jesus Christ is an offense to this world.
1 Corinthians 1:18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
Brethren, please stop supporting this error of a crossless gospel.
