Why Do You Kick at My Sacrifice?

In Deuteronomy 32 verse 15 in the Song of Moses, he's talking about Israel. He says that Jeshua and her Israel grew fat and kicked against God. In 1 Kings 2, right after the death of David, when Solomon becomes king, then Solomon banishes a priest by the name of a biothar who is a descendant of Eli. So long story short, this is the prophet coming in and saying, because you chose to honor your sons above me, you chose to treat my offerings with contempt.
