# if they had stood in my council meeting

Standing in Yahweh's council represents being one of those who meets with him to learn what he is thinking. This is a condition that is contrary to fact; the false prophets had not stood in his council meeting.

# had stood in my council meeting

See how you translated a similar phrase in Jeremiah 23:18.

# to turn from

This means they would stop doing these things.

# the wickedness of their practices

"the evil things they do." See how similar words are translated in Jeremiah 4:4.
