That sounds like it's from Thus Spake Zarathustra? It's translated that way intentionally, because Nietzsche wrote it to sound archaic and reminiscent of Old Testament language, on purpose, as a stylistic choice. The translators are accurately reflecting that. His version of Zarathustra is undoing the "mistake" of the original Zarathustra. You don't see this in translations of his other works, like The Gay Science or On The Genealogy of Morality, which are better introductions anyway, not being explicitly literary like Zarathustra.
