If iniquity be in thine hand - If you have in your possession anything that has been unjustly obtained. If you have oppressed the poor and the fatherless, and have what properly belongs to them, let it be restored. This is the obvious duty of one who comes to God to implore his favor; compare Luke 19:8.
