'Assured' in the Bible

“But as the time of the promise was approaching which God had assured to Abraham, the people increased and multiplied in Egypt,

and being fully assured that what God had promised, He was able also to perform.

Epaphras, who is one of your number, a bondslave of Jesus Christ, sends you his greetings, always laboring earnestly for you in his prayers, that you may stand perfect and fully assured in all the will of God.
