Midrasz do Liczb 3:21

Another interpretation (of Gen. 5:1): THIS IS THE BOOK < OF THE GENERATIONS OF ADAM >. This text is related (to Is. 41:2): WHO HAS WROUGHT AND DONE IT? THE ONE WHO NAMED THE GENERATIONS FROM THE BEGINNING. If the generations were worthy, the Holy One gave them their names just as he had given names to Adam and Eve. Thus it is stated (in Gen. 5:2): AND HE GAVE THEM THE NAME ADAM. You also find that when the Holy One sees a righteous one born, he gives him his name as a mark of honor. He named Noah because he was righteous, as stated (in Gen. 5:29): AND HE CALLED HIS NAME NOAH. He named Abraham, as stated (in Gen. 17:5): BUT YOUR NAME SHALL BE ABRAHAM. So also with Isaac, Jacob, Solomon, and Josiah. Thus it is stated (in I Kings 13:2): BEHOLD, A SON SHALL BE BORN UNTO THE HOUSE OF DAVID; JOSIAH SHALL BE HIS NAME. If the generations were worthy, he would give a name to each and every one; and from his name he would make known his works. Our masters have said:⁹⁰Cf. Yoma 83b; yRH 3:9 (59a). When R. Me'ir would see a person, he would learn his name, and from his name he would know his works. Once upon a time two students came to him, and one had the name Kidor. R. Me'ir said to his students: Beware of this Kidor. They said to him: He is a Torah scholar. He said to them: [Nevertheless], you yourselves beware of him. One day they went to the bathhouse and deposited their clothes with Kidor. He took their clothes and went away. When they came out, they did not find < him >. They went to their houses and put on other clothes. They came to R. Me'ir. R. Me'ir said to them: Why did you change your clothes? They said to him: We went to the bathhouse and deposited our clothes with Kidor, but he took them. He said to them: Did I not say to you: Beware of this man? They said to him: O our master, if you please, < tell us > how you knew. He said to them: From his name, for it is written (in Deut. 32:20): FOR (Ki) A GENERATION (dor) OF PERVERSITY ARE THEY…. So also you find in Egypt (in Numb. 3:21): THE LIBNITE FAMILY. At what time did he give them their names? When Pharaoh arose and worked them with clay and brick (rt.: LBN). Ergo: THE LIBNITE (rt.: LBN) FAMILY. (Deut. 32:20, cont.:) AND THE SHIMEITE (rt.: ShM') FAMILY. When they complained of the servitude, the Holy One heard (rt.: ShM') their prayer. (Deut. 32:27:) AND THE HEBRONITE (rt.: HBR) FAMILY, to whom the Divine Presence was allied (rt.: HBR). <These examples > are to teach you that if the generations were worthy, the Holy One would give them their names, as stated (in Is. 41:4): THE ONE WHO NAMED THE GENERATIONS….
