Just read Kings and Chronicles--Jews in David and Solomon's kingdom (including Solomon himself), in Hezekiah's kingdom, in Josiah's kingdom (just a few decades before the destruction of the first Temple), in the books of Jeremiah and Isaiah (among other prophets) were "henotheists," worshipping one god at a time. The distinction between monotheistic Jews and other peoples residing in "Eretz Yisrael" was not easily or quickly achieved. The process of Jews becoming monotheistic began with Ezra (thanks to the Persian emperor with whose authority Ezra spoke) and monotheism), suffered a setback under the Greeks, and only became the norm of the land under the Hasmoneans(mid 2nd-century BCE), who enforced mandatory circumcision.
