Those flying scorpion locusts from Revelation

They had tails and stings like scorpions, and in their tails they had power to torment people for five months. Rev 9:10

The ancient and honourable, he is the head; and the prophet that teacheth lies, he is the tail.
Isaiah 9:15

It seems our "creatures" tails are false prophets and false teachers of God's Word.
Precept upon precept.
