Hera
Background
Hera is the Queen of the Olympians. She is married to Zeus.
During the events of Jason and the Argonauts (1963) played by Honor Blackman
After King Pelias murders Briseis in her temple, Zeus promises Hera that King Pelias shall be punished for desecrating her temple and Hera asks to help Jason. Zeus agrees but only the amount of times Briseis asked for help, five times. Twenty years later, as King Pelias is riding his horse, Hera spooks the horse causing it to dump him in the water. Later, Jason is brought before The Olympians and Hera tells him that she shall help him five times. She then helps Jason by telling him where to find the Golden Fleece, by telling him where to sail to find the Isle of Bronze, how to kill Talos and finally revealing herself to the Argonauts and telling them where next to go and who to ask for help. She then helps Jason again by having Triton hold back the Clashing Rocks so that the Argo may pass them by.
