Iniquity - This does not directly mean sin. Though (apparently) the Greek word for iniquity and sin is the same, the Hebrew words for these are totally different. Iniquity refers to the heart not being holy - i.e. not set apart, not perfect, and not godly. It is the inclination of our hearts to do evil. Notice that Isaiah 59:1-2 highlights a difference between the two concepts, though related. Take a look at Psalm 51:5. We are born in iniquity, not sin. I am becoming convinced that a new born baby has not sinned per se, but rather, we are born in a state of separation of God. This separation is called iniquity, and we typically call this "born a sinner". The fact is, we, at birth, have inherited iniquity straight from Adam. So do babies go to hell if they die, or do they go to heaven (age of accountability)? I don't know!
Jealous - There are multiple definitions for the english word "jealous", and not all of them are negative. When referred to God, the original text translates to "one being vigilant in guarding a possession" (similar to zeal). For mankind, it can certainly be a Godly jealousy, be is typically either "hostile towards one believed to have an advantage" (similar to envy) or "disposed to suspect unfaithfulness" (the opposite of trust, which is a characteristic of love).
