Final answer:
The elders of the city and the leading men stood with Judah before the LORD.
Step-by-step explanation:
In the context of the question, the people who stood with Judah before the LORD were the elders of the city and the leading men. This is mentioned in the passage, "Then came the elders of the city and the leading men and they rescued the survivors."
These individuals stood with Judah before the LORD in the face of a riot against the Jews. The LORD confused the speech of those who had risen up against the Jews, and the elders and leading men acted to rescue the survivors.
