Almighty YHWH only chose one people to keep and teach His commands and ordinances. Yet, He is the Master of all.
2 Esdras 5:27-30
[27]And among all the multitudes of people thou hast gotten thee one people: and unto this people, whom thou lovedst, thou gavest a law that is approved of all.
[28]And now, O Lord, why hast thou given this one people over unto many? and upon the one root hast thou prepared others, and why hast thou scattered thy only one people among many?
[29]And they which did gainsay thy promises, and believed not thy covenants, have trodden them down.
[30]If thou didst so much hate thy people, yet shouldest thou punish them with thine own hands.
