Esias 45:6 In-Context

4 For the sake of my servant Jacob, and Israel mine elect, I will call thee by thy name, and accept thee: but thou hast not known me.
5 For I am the Lord God, and there is no other God beside me; I strengthened thee, and thou hast not known me.
6 That they that from the east and they that from the west may know that there is no God but me. I am the Lord God, and there is none beside.
7 I am he that prepared light, and formed darkness; who make peace, and create evil; I am the Lord God, that does all these things.
8 Let the heaven rejoice from above, and let the clouds rain righteousness: let the earth bring forth, and blossom mercy, and bring forth righteousness likewise: I am the Lord that created thee.
