This noun denotes injustice, wrongdoing, and violent unrighteousness—the opposite of the justice and equity God requires. It appears frequently in poetic texts describing both human wickedness and the character of those who oppose God. Hosea 10:9 uses it in the phrase 'sons of iniquity,' referring to evildoers. The term emphasizes the active, aggressive nature of sin—not mere moral failing but violent injustice that harms others. Psalms and prophets contrast this with God's righteousness, establishing iniquity as incompatible with God's presence and ultimately destined for judgment.
