I will place my rainbow in the clouds, and it will become a guarantee of the covenant between me and the earth.

Guarantee Your servant’s well-being;do not let the arrogant oppress me.

Do you really think that guarantees alone can withstand strategy and military strength? On whom are you now depending, that you're rebelling against me?
