Wherever the Jews were settled, they had their synagogues, their sacred Scriptures, their uncompromising belief in the One true God. Not only so: their synagogues everywhere attracted proselytes from the surrounding Gentile populations. The heathen religions were at that period in a state of utter collapse. The smaller nations had lost faith in their deities, because they had not been able to defend them from the victorious Greeks and Romans. But the conquerors had for other reasons equally lost faith in their own gods. It was an age of skepticism, religious decay and moral corruption.
