The Nine of Pentacles is the card of abundance, of comfort and security, but primarily, it is the card of self-sufficiency and independence. We feel good for what we have achieved and we enjoy the fruits of our efforts. The Knight of Swords is logical, witty, just, but he can also be impatient, judgmental, verbally aggressive. The combination and of the Nine of Pentacles and the Knight of Swords can predict disruptions caused by news or misunderstandings related to career or practical matters.
The elements of the cards are Earth (Nine of Pentacles) and Air (Knight of Swords). This combination gives poor results, as the Air card is trying to motivate the Earth card to move, but they can end up going around in circles, like a vortex of rotating air and dust. Eventually the dust will settle and we'll be able to see things with greater clarity.
