Now viewing scripture range from the book of Isaiah chapter 49:4 through chapter 49:5...
4 Then I said, I have laboured in vain, I have spent my strength for nought, and in vain: [yet] surely my judgment [is] with the LORD, and my work with my God.
5 And now, saith the LORD that formed me from the womb [to be] his servant, to bring Jacob again to him, Though Israel be not gathered, yet shall I be glorious in the eyes of the LORD, and my God shall be my strength.
