The Old Covenant had a ministry of condemnation and death. Read II Corinthians 3. Something you won't hear quoted much from Judaizers. They also won't quote the parts about those who are obsessed with the Old Covenant being blinded until God takes away the blindness. Note the underlined parts.
II Cor 3:
1Are we beginning to commend ourselves again? Or do we need, as some do, letters of recommendation to you, or from you?
2You yourselves are our letter of recommendation, written on our[SUP]
a[/SUP] hearts, to be known and read by all.
3And you show that you are a letter from Christ delivered by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.[SUP]

4Such is the confidence that we have through Christ toward God.
5Not that we are sufficient in ourselves to claim anything as coming from us, but our sufficiency is from God,
6who has made us sufficient to be
ministers of a new covenant, not of the letter but of the Spirit. For the letter kills, but the Spirit gives life.
7Now if
the ministry of death, carved in letters on stone, came with such glory that the Israelites could not gaze at Moses’ face because of its glory, which was being brought to an end,
8will not
the ministry of the Spirit have even more glory?
9For if there was glory in
the ministry of condemnation,
the ministry of righteousness must far exceed it in glory.
10Indeed, in this case, what once had glory has come to have no glory at all, because of the glory that surpasses it.
11For if what was being brought to an end came with glory, much more will what is permanent have glory.
12Since we have such a hope, we are very bold,
13not like Moses, who would put a veil over his face so that the Israelites might not gaze at the outcome of what was being brought to an end.
14But their minds were hardened.
For to this day, when they read the old covenant, that same veil remains unlifted, because only through Christ is it taken away. 15Yes, to this day whenever Moses is read a veil lies over their hearts. 16But when one[SUP]c[/SUP] turns to the Lord, the veil is removed. 17Now the Lord[SUP]
d[/SUP] is the Spirit, and where the Spirit of the Lord is, there is freedom.
18And we all, with unveiled face, beholding the glory of the Lord,[SUP]
e[/SUP] are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.
By the way, God also was going to kill Moses for not circumcising his son, so the same penalty apparently applied to circumcision. Like the Sabbath, circumcision was a sign of the Old Covenant. As we have discussed, the Old Covenant is between God and Israel, not between God and Christians.
Exodus 4:
24At a lodging place on the way the Lord met him and sought to put him to death.
25Then Zipporah took a flint and cut off her son’s foreskin and touched Moses’[SUP]
c[/SUP] feet with it and said, “Surely you are a bridegroom of blood to me!”
26So he let him alone. It was then that she said, “A bridegroom of blood,” because of the circumcision.
