“What have I to do with you.” An idiomatic phrase that in essence means “What do we have in common.” The woman now saw herself as very different from the man of God, who in her mind has brought the wrath of God upon her house.
“bring my sin to mind.” The specific sin or sins the woman had in mind is not important. The point is the humble people are aware of their sins and shortcomings, and this woman was too. Everyone sins, but humble people take responsibility for their sins and try to rectify them.
