Name of Tzadik like G-d's

 Bamidbar Rabbah (02:12) When G-d created the world. Twenty generations came and went, but no good was found in them, neither did a single righteous man rise up among them. Beyond the twenty generations G-d espied Abraham, deposited in the land of Babylon, which is called distant; as it is said, They are come from a far country unto me, even from Babylon. G-d thought, ‘Can one be certain that he will have the power to stand?’ When he was cast into the fiery furnace and sanctified the name of G-d and thus stood his test, G-d immediately brought him to the Land of Israel where he built an inn for himself, gave food to wayfarers, and brought men beneath the wings of the Shechinah, making known the glory of G-d throughout the world, and causing his own name to bear a resemblance to the name G-d, like the angels.
