What nations around Judah were more loyal to their gods than Judah was to her true God?

Answer 1

This is a loaded question, but the answer must vary according to the period of time considered. If the loyalty required is loyalty to Yahweh alone, as the God of Judah, then arguably all its neighbours were more loyal to their gods.

Prior to the seventh-century BCE reign of King Josiah, Judah largely worshipped exactly the same gods as its neighbours, with the only significant difference being that Yahweh was the chief god in the Judahite pantheon. Josiah instituted religious reforms that made the worship of only one God, Yahweh, the state religion. Hwever, the later prophets seem to suggest that polytheism survived among the people until at least the time of the Babylonian Exile. Up to the fifth century BCE, it would be difficult to say that the Judahites were "more loyal to their true God."

Even after the Babylonian Exile, and until the end of the first century CE, a spirit or goddess called Wisdom, sometimes Lady Wisdom, was revered among the Jews. The Book of Proverbs says that Wisdom was present at the creation, and Wisdom is even mentioned in the New Testament Gospels. Depending on whether Wisdom is considered to dilute Jewish monotheism, the Jews could still not be regarded as "more loyal to their true God."
