Amos 3:3 Can two walk together, except they be agreed?
Birds of a feather flock together. The Peruvians used to say, Tell me who you run around with and I will tell you who you are!
There is great truth here. These two meet and walk together because they want to. They are on the same path. They have the same conversation. They are doing the same things.
Even if you are not like them the more you hang around them the more like them you will become.
It is imperative that you choose your friends wisely. Know that you become like who you hang around so choose wisely!
