Nothing more about this incident is recorded any other place in the New Testament. We do not know specifically who the people were who were killed and we do not know the occasion upon which this tragedy occurred. Apparently however, there had recently been a confrontation with the Roman soldiers in the temple at the time of a sacrifice. The outcome of this incident was that some of the Galileans present at the temple were killed by the Romans, perhaps right at the altar, since there is a mention of the blood of the people mingling with the blood of the animal sacrifices.
Although we know none of the details, this all certainly does sound like a horrendous event. It was an event that was not only politically motivated, but there were also religious overtones included in the circumstances. It affected the residents in much the same way as we react when we are shown pictures of Americans who have been decapitated by the Islamic State Terrorists. Even more so, since these people of Galilee probably had even closer ties with those killed.
“Were these Galileans worse sinners than all the others?” the people asked Jesus.
In their struggle to make sense of the events that had occurred, this was their question. “Why did these people suffer in such a horrifying way? Was it because these who were murdered were especially bad themselves?” The questioners were implying that perhaps those people were so bad that God had allowed them to be killed.
