'Comfortably' in the Bible

"You have shed a lot of blood and fought great battles. You won't be building a house for my name, since you have shed so much blood on the earth in my sight. But look! A son born to you will live comfortably, because I will give him rest from all his enemies that surround him on every side, since his name will be "Solomon" - I will give peace and quiet for Israel during his lifetime.
