Noachides (or Bnai Noach) are righteous gentiles who observe The Seven Universal Commandments of the Biblical Covenant that G-d made with Noah as taught in Orthodox Judaism.
The Biblical Covenant of Noah (symbolized by the rainbow) is a Divine promise to never again destroy humanity. The Talmud informs us that in return for this promise, all humanity must observe the Seven Noachide Commandments. This is the Divine plan for world peace.
‘For, from the rising of the sun until its setting, My Name is great among the nations, and everywhere offerings are burnt and offered up to My Name; yea, a pure oblation, for My Name is great among the nations, says the Lord of Hosts.’
The Prophet Jeremiah said that in the end-days, the Gentiles will turn to G-d, coming from the ends of the earth to seek Him. 19. O G-d, my strength and stronghold, my refuge in times of trouble, nations will come to You from the ends of the earth, and they will say: “Our ancestors inherited falsehood,* useless nonsense. 20. Can a man make for himself gods? Such are no gods!” 21. Therefore, I will inform them this time and let them know My might and power, and they will know that My name is G-d.*** i.e. our ancestors religions are false.** They will learn I am omnipotent.
60. So that all the nations of the earth shall know the Lord is G-d; there is none else.61. Let your heart therefore be whole with the Lord our G-d, to follow His statutes and to keep His commandments, as of this day.
