Final Answer:

Phineas knew the Argonauts would help him because they had sworn an oath to assist anyone who needed their aid, as they were bound by their code of honor and camaraderie.

Explanation:

Phineas' confidence in the Argonauts' assistance stems from the deep-rooted code of honor and duty among the crew members. The Argonauts, led by Jason, were bound by a sworn oath to aid anyone who sought their help.

This oath was a foundational aspect of their brotherhood, and they upheld it with unwavering dedication. Consequently, when Phineas approached them seeking assistance, he did so with the assurance that they would honor their commitment.

Moreover, the Argonauts' reputation for valor and loyalty precedes them. Throughout their adventures, they had demonstrated their willingness to face formidable challenges and support those in need.

This track record further solidified Phineas' belief that they would come to his aid when he called upon them. Thus, Phineas' confidence was not merely based on wishful thinking but on a well-established understanding of the Argonauts' principles and past actions.

In summary, Phineas' assurance in the Argonauts' assistance was grounded in their sworn oath of support and their established reputation for bravery and loyalty. These factors combined to form a strong foundation of trust, allowing Phineas to rely confidently on their aid in his time of need.
