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.

Exodus 28:9-14
9
You shall take two onyx stones, and engrave on them the names of the children of Israel:
10
six of their names on the one stone, and the names of the six that remain on the other stone, in the order of their birth.
11
With the work of an engraver in stone, like the engravings of a signet, you shall engrave the two stones, according to the names of the children of Israel: you shall make them to be enclosed in settings of gold.
12
You shall put the two stones on the shoulder straps of the ephod, to be stones of memorial for the children of Israel: and Aaron shall bear their names before Yahweh on his two shoulders for a memorial.
13
You shall make settings of gold,
14
and two chains of pure gold; you shall make them like cords of braided work: and you shall put the braided chains on the settings.
