It is a book that needs to know how to read Hebrew unvoiced, that pronounce it. In fact, I do not know what it is, because if we know already read Hebrew unvoiced, normally we already know these phrases. Additionally, these phrases can help us to make do in the country since we are delivered in bulk, without rows or by topic or by nothing at all!
Who can tell me what this book has served him so I do the same?
