International Standard Bible Encyclopedia [4]
a - mis ´: There are two words translated "amiss" in the New Testament, ἄτοπος , átopos , referring to that which is improper or harmful ( Luke 23:41; Acts 28:6 ), while κακῶς , kakō̇s , refers to that which is evil in the sense of a disaster, then to that which is wicked, morally wrong. This latter is the use of it in James 4:3 . The purpose of the prayer is evil, it is therefore amiss and cannot be granted (compare 2 Chronicles 6:37 ).
