Q: Was there an object called the Altar of Incense at the Temple? A: Yes
Q: Can flies spread disease by biting people and such? A: yes.
Ok, you can hopefully understand where I’m going with this line of reasoning.
Does the Bible directly say anywhere that the purpose of the Altar of Incense was to chase away the flies? No.
Matthew 12:24, 26
24 But when the Pharisees heard it, they said, This fellow doth not cast out devils, but by Beelzebub the prince of the devils.
26 And if Satan cast out Satan, he is divided against himself; how shall then his kingdom stand?
When retranslating devils, Beelzebub, Satan, as being flies the argument suggests that preventing disease and a plague of flies is the purpose. Nobody wants to get into an in-depth theological argument about flies and the nature of reality because it contradicts the rational foundations of monotheism without construed reasons of dispensationalism. Who wants to be the master of the flies? Mankind was given dominion over all the living creatures on Earth, hence becoming also the lord of the flies, Beelzebub.
Genesis 1:26
Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground.”
