For those who believe God knows the future:

Jer 18:7 The instant I speak concerning a nation and concerning a kingdom, to pluck up, to pull down, and to destroy it,
Jer 18:8 if that nation against whom I have spoken turns from its evil, I will relent of the disaster that I thought to bring upon it.

What does “thought to bring” mean?

What would a casual reader believe it means?
