A study of " those who are firmly rooted in knowledge" in commentator's viewpoint

In Nisa: 162 and Ale Imran: 7 have been referred to “those who are firmly rooted in knowledge” in Quran. This question that “who are firmly rooted in knowledge?” has been discussed in this paper. In the first verse, “firmly rooted” means some of Bani-Israel’s religious scholars, but in the second verse, there is a difference opinion among commentators. Some believes that “firmly rooted” are Ahlul-Bayt (SA) and some believe that they are those who except Ahlul-Bayt (SA). As a result, we can say that “firmly rooted” has two meanings; a general meaning which it includes all people and a particular meaning which it includes Ahlul-Bayt (SA).
