Keep Away Or Must not Associate with Who?

Make note:

“But now I am writing to you that you must not associate with anyone who claims to be a brother or sister but is sexually immoral or greedy, an idolater or slanderer, a drunkard or swindler. Do not even eat with such people.” 
~ 1 Cor. 5:11

“In the name of the Lord Jesus Christ, we command you, brothers and sisters, to keep away from every believer who is idle and disruptive and does not live according to the teaching you received from us.” ~ 2 Thessalonians 3:6 ///
