The "law of first-mention" is the principle in the interpretation of Scripture which states that the first mention or occurrence of a subject in Scripture establishes an unchangeable pattern, with that
subject remaining unchanged in the mind of God throughout Scripture.
And example of The Law of First Meniton is when God changed Abram’s name to Abraham and made him the father of many nations.
God changed Sarai’s name to Sarah and made her the mother of nations.
changed Jacob’s name to Israel and made him the first Israeli.
God changed the name of Simon to Peter and gave him primacy over the other apostles.
Whenever God changed the name, the person was given great honor.
