Father and mother are treated with contempt. Within your walls the foreign resident is exploited, the fatherless and the widow are oppressed.
KJV
In thee have they set light by father and mother: in the midst of thee have they dealt by oppression with the stranger: in thee have they vexed the fatherless and the widow.
ASV
In thee have they set light by father and mother; in the midst of thee have they dealt by oppression with the sojourner; in thee have they wronged the fatherless and the widow.
