What was Esther's (of the Book of Esther) covenant with God?

was it that she had deep faith and trust in him to help her through all of difficult times?

Why is her covenant with God so important?

was it because she needed/ relied on her faith and God to guide her/ give her courage when she was saving the Persian Jews?

Are these answers OK? Is there anything I'm missing? any sites I should look at?
thanks

I have some difficulty. God is not mentioned, as I recall in Esther. Esther did ask Jews to fast and pray for three days, after which she went before the King, and he found favor to hear her.

So perhaps you are right, but it is not really clear to me based on the readings.
Ok,thank you.
