In my Douay-Rheims Bible at Psalm 58 it refers to the Jews at the enemy of Christ.
Did the word enemy have a different meaning in the 16th century?

In Jesus’ time, there was the Jewish populace, and there was the Jewish leadership.
The leadership was the group that intended to eliminate Jesus because he was growing
in favor with the people and they were concerned that they might lose their control
and place among the people. These were the scribes, pharisees, and ruling class.
When Jesus spoke of the Jews in a negative way, it was this group. As an example
once when the apostles were going up to Jerusalem to celebrate a Jewish holy day,
Jesus said something to the effect that he didn’t want to go with them right now for
the Jews were looking for him. Then Jesus sent them on their way, and he followed
them later on. He didn’t mean the populace, but the Jewish leadership.
In reading the Bible, when this distinction of “Jews” is kept in mind, it helps.
At other times the reference to the people or the leadership is not so clear.
Just a thought.
