Webster defines repent as:
a : to feel regret or contrition b : to change one's mind
I have ALWAYS heard repent used in the second sense or to "change direction" (e.g. God changed His mind.). But in fairness, looking back through these posts are you using the term "repent" in the first sense? (e.g. God felt regret.) Which term are you using? How do you use repent in terms of God?
So now we rely on Websters to resolve our spiritual paradoxes, huh? I don't think we can or should turn to a secular dictionary to resolve this dilemma.
If the Bible explicitly says that God "repented" and if the Bible explicitly states that God does not change his mind, then obviously where it concerns God, to "repent" does not mean to "change one's mind."
By your dictionary we are left with regret or contrition, which would imply that God made a mistake. But God does not make mistakes, does he?
I don't think Webster's is going to resolve the paradox.
Do you deny that God "repented"? If not then are you willing to pick from "a" or "b"?
Or do you think that maybe there's some things we mortals just can't understand?
