'Iniquity' in the Bible

the man shall then bring his wife to the priest, and shall bring as an offering for her one-tenth of an ephah of barley meal; he shall not pour oil on it nor put frankincense on it, for it is a grain offering of jealousy, a grain offering of memorial, a reminder of iniquity.

‘The Lord is slow to anger and abundant in lovingkindness, forgiving iniquity and transgression; but He will by no means clear the guilty, visiting the iniquity of the fathers on the children to the third and the fourth generations.’

Pardon, I pray, the iniquity of this people according to the greatness of Your lovingkindness, just as You also have forgiven this people, from Egypt even until now.”

Only the Levites shall perform the service of the tent of meeting, and they shall bear their iniquity; it shall be a perpetual statute throughout your generations, and among the sons of Israel they shall have no inheritance.
