How did Hercules use an oracle?

Hercules consulted the Oracle of Delphi for guidance on how to atone for the tragic act of killing his family, driven mad by Hera. The oracle instructed him to serve King Eurystheus and complete a series of twelve labors, which were meant to be nearly impossible tasks. These labors not only tested his strength and courage but also served as a path to redemption and ultimately his acceptance among the gods.
