Esias 48:15

15 I have spoken, I have called, I have brought him, and made his way prosperous.

Esias 48:15 In-Context

13 My hand also has founded the earth, and my right hand has fixed the sky: I will call them, and they shall stand together.
14 And all shall be gathered, and shall hear: who has told them these things? Out of love to thee I have fulfilled thy desire on Babylon, to abolish the seed of the Chaldeans.
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.
