I tell you truly

"I tell you the truth." This adds emphasis to what Jesus says next.

whatever things you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven

"God in heaven will bind whatever you bind on earth and loose whatever you loose on earth" or "God in heaven will approve whatever you forbid or allow on earth"
