Iniquity, transgression and sin
In the Word three terms are used to refer to bad actions: transgression, iniquity, and sin. Transgression is the least bad. It means a violation of what is true in an external context, a violation of what is right and orderly. Iniquity is next and denotes acts that violate more interior truths. Sin is the worst. It is a violation of what is holy and righteous, a violation against the Lord. Sin is the deepest kind of evil. Regarding iniquity -- to be in charity, or live a life of charity is to live a life where the acts and thoughts that have top priority are those that have within them a love for the neighbor. Sometimes our love of self, our inborn desire to put ourselves first, is stronger than our charity and we do something for ourselves at the expense of our neighbor, or even do harm to our neighbor. Such an act, if our motive is selfish, is an iniquity.

Leviticus 5:17-18
17
"If anyone sins, and does any of the things which Yahweh has commanded not to be done; though he didn't know it, yet he is guilty, and shall bear his iniquity.
18
He shall bring a ram without blemish from of the flock, according to your estimation, for a trespass offering, to the priest; and the priest shall make atonement for him concerning the thing in which he sinned and didn't know it, and he will be forgiven.
