Tower card for past life's purpose

I am totally stumped. To get the whole picture

1. A card to describe me in a relevant past life (KNAVE OF SWORDS REVERSED)

2. My purpose during that lifetime (THE TOWER..)

3. A lesson I didn't not complete in that life (4 OF WANDS)

4. How is that relevant to my current life (3 OF CUPS)

Like im super stumped but it feels right pls help LOL
