Nowhere in the Bible does it say this. "The two love commands" are from the writings of Moses.
Jesus says it, and Paul says it - love fulfills all the law and the prophets.
The two love commands are in the Old Testament, but are not called THE COVENANT as the Decalogue is.
The two love commands are the essence and substance of Gods law, the Decalogue was not, the Decalogue brings death, but the spirit brings life.
You need to read 2 Corinthians chapter three, where Paul says the apostles are the ministers of the new covenant and the law of the Spirit that gives life, which he compares with the ten commands, given to Moses on the mountain, that brings death and have passed away.
The Ten Commands are called the ministration of DEATH, the letter which KILLS, and the ministration of CONDEMNATION.
2Co 3:6 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.
2Co 3:7 But if the ministration OF DEATH
written and engraved in stones (The Ten Commandments) 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:
2Co 3:8 How shall not the ministration of the spirit be rather glorious?
2Co 3:9 For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.
2Co 3:10 For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
2Co 3:11 For if that which is DONE AWAY was glorious, much more that which remaineth isglorious.
The Decalogue has been ended, being replaced by the essence of Gods law the law of love - there’s not one drop of love for your neighbor in any of the ten commands.
The reason the Ten commands kills, brings death, and condemnation, and has been done away, is due to the fact that the penalty under the law for breaking any of the Ten, was being put to death by stoning.
The penalty for homicide - being put to death by stoning:
Exo 21:12 He that smiteth a man, so that he die, shall be surely put to death.
The penalty for not honoring your mother and father: put to death by stoning:
Lev 20:9 For every one that curseth his father or his mother shall be surely put todeath: he hath cursed his father or his mother; his blood shall beupon him.
The penalty for adultery: put to death by stoning:
Lev 20:10 And the man that committeth adultery with anotherman's wife, even hethat committeth adultery with his neighbour's wife, the adulterer and the adulteress shall surely be put to death.
The penalty for breaking the sabbath by doing any work, such as picking up sticks for kindling: put to death by stoning:
Exo 31:14 Ye shall keep the sabbath therefore; for it isholy unto you: every one that defileth it shall surely be put to death: for whosoever doeth anywork therein, that soul shall be cut off from among his people.
If the Ten Commands are still in effect, then the penalty for breaking them is still in effect as called for BY the law, thus those who insist on keeping the ended covenant that contained the Ten Commands, are breaking the law themselves, by not stoning to death those who break the commands.
