The trial means a test and affliction from Allah (swt) to the people of the Children of Israel, as a result of their killing and denial of the prophets (PBUT), so they became blind and deaf. You are responsible for the means of perception and Allah (swt) will ask you about them. Although hearing always takes precedence over sight, but here it comes after the sight to indicate the blindness of the heart; Because the experience that a person sees is truer than the experience that he hears. Therefore, the test will be first by what you saw, and then by what you heard, and what you reported. And as it is known, they committed all crimes; they worshiped the calf, and demanded to see Allah (swt) publicly, and they quarreled with the prophets and denied them, and even killed them. Moreover, every time Allah (swt) accepted their repentance and pardoned them, they returned to the do the same of what they had done because of the blindness in their hearts.
