Psalm 26:4-5 I do not sit with the deceitful, nor do I associate with hypocrites.  I abhor the assembly of evildoers and refuse to sit with the wicked.
I think we all need to take these verses to heart. We need to be careful of who we hang around with. We don’t have to stay away from all of the people who are unbelievers all the time, but I wouldn’t spend the majority of my time with them. Most of my friends are from church, then I have a few close friends from school. Other than that, I have more of acquaintances. Be careful, and pray for discernment!
Proverbs 22:24-25 Do not make friends with a hot-tempered person, do not associate with one easily angered,  or you may learn their ways and get yourself ensnared.
