They trusted to human reasoning, thinking they were clinging to the truth and to sound logic and theory (17:9), and this led them to believe the lie that they were right and God's messenger was wrong.
Sila’y nagsitiwala sa katwiran ng tao, na iniisip na sila’y naghahawak sa katotohanan at sa mga haka-haka at teorya (17:9) at ito ang nagtulak sa kanila na paniwalaan ang kasinungalingan na sila’y matuwid at ang mensahero ng Dios ay mali.
