Were all the Laws revealed at once?
In the ancient time, the full righteousness of the law was not revealed as it is in these end times. Noah gave his children the instructions of the commands which he knew because all was not revealed to him by evidence of the laws that Moses received on Mt. Sinai that gave more understanding of the righteousness of Alahayim.
And in the thirty fourth jubilee Noah began to enjoin upon his sons' sons the ordinances and commandments, and all the judgments that he knew, and he exhorted his sons to observe righteousness, and to cover the shame of their flesh, and to bless their Creator, and honour father and mother, and love their neighbour, and guard their souls from fornication and uncleanness and all iniquity.
A good example to understand how the whole righteousness of the law was revealed over a progression of time is the process of the revelation 0f the Feast of Tabernacles. The feast started in the earth with Abraham for seven days and was not a feast that Noah was aware of. Then the fullness of the feast's 8 days of celebration was not revealed to Abraham either because it was not until the days of Jacob that the fullness of the feast of Tabernacles was revealed.
And Jacob said: 'Lord, how can I remember all that I have read and seen? 'And he said unto him: 'I will bring all things to thy remembrance.'
And he went up from him, and he awoke from his sleep, and he remembered everything which he had read and seen, and he wrote down all the words which he had read and seen.
And he celebrated there yet another day, and he sacrificed thereon according to all that he sacrificed on the former days, and called its name 'Addition,' for this day was added and the former days he called 'The Feast '.
And thus it was manifested that it should be, and it is written on the heavenly tablets: wherefore it was revealed to him that he should celebrate it, and add it to the seven days of the feast.
And its name was called 'Addition,' because that it was recorded amongst the days of the feast days, according to the number of the days of the year.
The laws of fornication is also a good example of how the fullness of the laws weren't revealed all at once because the whole law wasn't revealed until Moses received the whole law on Mount Sinai. Hence its unlawful to have certain marriages after Moses received the law that were not unlawful before that time. For example:
Simeon married his sister Dinah, [Jasher 45:2] but it is now unlawful to do so and much less even to see one's sister's nakedness.
Leviticus 18:The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, whether she be born at home, or born abroad, even their nakedness thou shalt not uncover.
Moses' father, Amram, married his aunt, Jochbed, [Exo 6:20] but now it is unlawful to do so and much less even see her nakedness.
Leviticus 18:12 Thou shalt not uncover the nakedness of thy father's sister: she is thy father's near kinswoman.
Jacob married two sisters in the same lifetime, [ Jasher 28:28] but now it is unlawful to do so.
Leviticus 18:18 Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time.
The testimonies show that the law had not been revealed in its completeness from the beginning until the completeness was revealed to Moses.
For until that time there had not been revealed the ordinance and judgment and law in its completeness for all, but in thy days (it has been revealed) as a law of seasons and of days, and an everlasting law for the everlasting generations.
Yet and still, the grace and truth of the Law of Moses was revealed by Christ Yache the Lord:
For the law was given by Moses, but grace and truth came by Yache Christ.
Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
Ye have heard that it was said by them of old time, Thou shalt not commit adultery:
But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
It hath been said, Whosoever shall put away his wife, let him give her a writing of divorcement:
But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.
Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths:
But I say unto you, Swear not at all; neither by heaven; for it is Alahayim's throne:
But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.
After Yache resurrected, he gave his Apostles, commands to teach all nations whatsoever he commanded, hence the Apostles commands are of the Lord Yache and give us further understanding of the righteousness of the Law.
And Yache came and spake unto them, saying, All power is given unto me in heaven and in earth.
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit:
Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
• Thus the letters of the Apostles give us the Lord's commandments:
2 Peter 3:1-2
This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance:
That ye may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us the apostles of the Lord and Saviour
I Cor 14:37
If any man think himself to be a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandments of the Lord.
• The believers after the Apostles had respect unto all the Records.
Ignatius to Philadelphia
.......But your prayer will make me perfect [unto Alahayim], that I may attain unto the inheritance wherein I have found mercy, taking refuge in the Gospel as the flesh of Yache and in the Apostles as the presbytery of the Church.
5:2 Yea, and we love the prophets also, because they too pointed to the Gospel in their preaching and set their hope on Him and awaited Him; in whom also having faith they were saved in the unity of Yache Christ, being worthy of all love and admiration as holy men, approved of Yache Christ and numbered together in the Gospel of our common hope.
8:2 Because I have heard of some who say; unless I find it written in the charters, I will not believe it to be written in the Gospel. And when I said, It is written; they answered me, That remains to be to be proved.
The some didn't believe the Gospel just as they struggle to believe today:
9:2 But the Gospel hath a singular preeminence in the advent of the Saviour, even our Lord Yache Christ, and His passion and resurrection. For the beloved Prophets in their preaching pointed to Him; but the Gospel is the completion of immortality. All things together are good, if ye believe through love.
The epistle of Polycarp to the Philipians chapter 2:19-20
19 Let us therefore serve him in fear, and with all reverence as both himself hath commanded; and as the Apostles who have preached the Gospel unto us, and the prophets who have foretold the coming of our Lord have taught us.
In closing, the laws were revealed unto Moses and the fullness of the understanding of the laws and the rest of the commands are being revealed by Yache the Lawgiver of Judah (Gen 49:10) through his Apostles and disciples in these end times.
