You don't know this and you probably cannot agree with this but the ESV, the NKJV, NASV, all tell a lie in Hebrews 9:26. They say that the appearance of Jesus Christ to Israel at his first coming was the consummation of the ages. The KJV does not make such a claim. It says this was the end a singular age, the age of the law of Moses as God's operative principle of divine dealing with them as a people. The entire NT scriptures backs this KJV rendering up.
NASB Heb 9:26 Otherwise, He would have needed to suffer often since the foundation of the world; but now once at the consummation of the ages He has been revealed to put away sin by the sacrifice of Himself.
ESV
for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself.
NKJV 26 He then would have had to suffer often since the foundation of the world; but now, once at the end of the ages, He has appeared to put away sin by the sacrifice of Himself.
26 For then must he often have suffered since the foundation of the world, but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
Romans 10:4
For Christ is the end of the law to everyone that believeth (as opposed to worketh).
2 Cor 3:1 Do we begin again to commend ourselves? or need we, as some others, epistles of commendation to you, or letters of commendation from you?
2 Ye are our epistle written in our hearts, known and read of all men:
3 Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.
4 And such trust have we through Christ to God-ward:
5 Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;
6 Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.
7 But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
8 How shall not the ministration of the spirit be rather glorious?
9 For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.
10 For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
11 For if that which is done away was glorious, much more that which remaineth is glorious.
12 Seeing then that we have such hope, we use great plainness of speech:
13 And not as Moses, which put a veil over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:
14 But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.
15 But even unto this day, when Moses is read, the vail is upon their heart.
16 Nevertheless when it shall turn to the Lord, the vail shall be taken away.
17 Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty.
18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
The end of the law ended the age but there are still ages to come.
Ephesians 2:7
That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
