Pentacles is about money

Just like Abba says

Money, money, money
Must be funny
In the rich man's world
Money, money, money
Always sunny
In the rich man's world

Knight of Pentacles is telling you, you night receive the news you have been waiting for so long. It'll be positive news, most possibly you'll receive some money .
.


Knight of Pentacles is also asking you to give importance to your daily life, the things you do daily.
