Isaiah 60:14 - Ellicott's Commentary On The Whole Bible

The sons also of them that afflicted thee... — The explanation commonly given is that the “sons” are named because the persecutors themselves are thought of as no more. It seems better, however, to see in the words an expression of the law of inherited retribution, which entered so largely into the Hebrew’s thought of the moral government of the world. That law will show itself in the prostrate homage with which the descendants of the old oppressors will recognise that the restored city is indeed the Zion of the Holy One of Israel.
