Esias 48:17 In-Context

15 I have spoken, I have called, I have brought him, and made his way prosperous.
16 Draw nigh to me, and hear ye these words; I have not spoken in secret from the beginning: when it took place, there was I, and now the Lord, the Lord, and his Spirit, hath sent me.
17 Thus saith the Lord that delivered thee, the Holy One of Israel; I am thy God, I have shewn thee how thou shouldest find the way wherein thou shouldest walk.
18 And if thou hadst hearkened to my commandments, would thy peace have been like a river, and thy righteousness as a wave of the sea.
19 Thy seed also would have been as the sand, and the offspring of thy belly as the dust of the ground: neither now shalt thou by any means be utterly destroyed, neither shall thy name perish before me.
