Yashaʿyahu 43:10–13 (Isaiah)
"You are My ʿAdim," declares Yahuah, "and My servant whom I have chosen, so that you may Yada and Aman Me and understand that I am He. Before Me no Al was formed, and after Me there shall be none. I, I am Yahuah, and besides Me there is no Mushiʿ. I declared, I Yashaʿ, and I caused it to be heard, and there was no foreign mighty one among you. Therefore you are My ʿAdim," declares Yahuah, "that I am Al. Even from the day, I am He. There is none who can deliver from My hand. I act, and who can turn it back?"
