Now, O Lord, God of Israel, keep the promise you made to your servant, my father David, when you said, 'You will never fail to have a successor ruling before me on the throne of Israel, provided that your descendants watch their step and serve me as you have done.'

"But if you or your sons ever turn away from me, fail to obey the regulations and rules I instructed you to keep, and decide to serve and worship other gods,

You must obey all I command you to do, follow my instructions, do what I approve, and keep my rules and commandments, like my servant David did. Then I will be with you and establish for you a lasting dynasty, as I did for David; I will give you Israel.

Ahab told Obadiah, "Go through the land to all the springs and valleys. Maybe we can find some grazing areas so we can keep the horses and mules alive and not have to kill some of the animals."
