The plague of frogs: symbolize the counterfeit gift of tongues

Exodus 8:1-15
The plague of frogs: after seven days later.
Aaron stretch out his hand with his staff over the streams ad canals and ponds, and make frogs come up on the land of Egypt.
Pharaoh summoned Moses and Aaron and said, "Pray to the Lord to take the frogs away from me and my people, and I will let your people go to offer sacrifices to the Lord."
But when Pharaoh saw that there was relief, he hardened his heart and would not listen to Moses and Aaron, just as Lord had said.
Seven days later, frog, driven from the river banks by the rotting fish, seek shelter in the houses.
Why?
This is the Second plague after the blood water in Nile and rivers, ponds.
This time Pharaoh felt it is troubled him and his people.
Frogs capture their prey with their tongues, which may symbolize the counterfeit gift of tongues that is sweeping the world today. Please remember that miracles, including the gift of tongues, prove only one thing – supernatural power. And the Bible informs us that supernatural power can come from either God or Satan.  Satan, who can pose as an angel of light from heaven (2 Corinthians 11:13-15), will utilize supernatural miracles so effectively that almost the entire world will be deceived and follow him (Revelation 13:3). At the present, he is using the counterfeit gift of tongues to join together churches and religions – including pagans and spirit worshipers.
How?
Keep holding a pure heart and mind, please give me a pure heart and discerning the way of God.
