The name Jew is derived from Yehudah, which means: ""He shall exalt."
This signifies that the Jew is "the one who exalts Hashem." This was intended by our mother Leah when she bestowed this name on her son Judah: "Now I will exalt Hashem, therefore she called his name Judah" (Breshis 29: 35). In his name the Jew declares his function. "This people have I created for Me that they relate My praise" (Isaiah 43:21). — Awake, My Glory
