According to the author Lynn Picknett there were around 40 men claiming to be the Messiah, hence the parody of Monty Python's Life of Brian. They were waiting for him.Is it possible a couple of these men were walking along and it was the Fishers who realised that Jesus was the true one ?
Messiah meant annointed Think of a concept Like crown prince. So in a state controlled by an outside power, Rome, you had all the aristocratic families vying for their sons to attain power. So 40 potential messiahs are quite possible. I suggest that the “Fishers” or fishermen were acolytes in a religious system like monks or friars. They had a job saving and converting people, not catching fish!
On another note I know nothing of those ancient languages, but the use of the plural is usual in so many.For example if introduced in French one says Vous, the plural of You, and drops to Tu when informal.The same in Germany, where a Police Officer must be spoken to as You plural.We had Thee and Thou but lost it. It is a note of Respect.So could they have referred to Jesus in the plural as a mark of honour , much like Her Majesty for our Queen ? Just a thought.
The ancient world was quite hierarchical, so the plural usages came from the needs of hierarchy. The term “god” or “son of god” could also have been used as such an honorific.
