Isaiah 47:9

The loss of children probably refers to their death in battle. Or that they would become prisoners in a foreign country.

• A widow had to depend upon her children for financial help. There were no state funds. To lose her children too would cause hopeless despair for her.

• The loss of the young soldiers from Babylon would cause the total defeat of the whole city. Babylon would become like a weak widow who has nobody to assist her.
