Paul says the basis for edification is understanding. He says tongue speakers edify themselves. And they should interpret so all can be edified (understand) = Tongue speakers knew what they were saying. Nothing like this today.
1 cor 14:2 say there is gift in tounge that No body know, and you do not believe It don't you.
Read the context brother
If you do speak in tounge in public than interpretation are needed, in private you can exercise gift in tounge without interpretation
So this verse do not say gift in tounge cease
