And how thrilling it was for me to be at the Columbus, Ohio, convention in 1931 when Brother Rutherford submitted the ‘new name’ Jehovah’s Witnesses, and all of us adopted it enthusiastically! Immediately afterward, all the congregations of Jehovah’s people around the globe adopted that ‘new name.’—Compare Isaiah 62:2.

Although the evidence points persuasively to Jehovah’s direction in selection of the name Jehovah’s Witnesses, The Watchtower (February 1, 1944, pp. 42-3; October 1, 1957, p. 607) and the book “New Heavens and a New Earth” (pp. 231-7) later pointed out that this name is not the “new name” referred to at Isaiah 62:2

What does Jehovah have in mind for Zion, his heavenly “woman,” represented by ancient Jerusalem? He states: “The nations will certainly see your righteousness, O woman, and all kings your glory. And you will actually be called by a new name, which the very mouth of Jehovah will designate.” (Isaiah 62:2)
Jehovah now confirms the changed condition of Zion by giving her a new name. That new name signifies the blessed condition and honored status enjoyed by Zion’s earthly children beginning in 537 B.C.E. It shows that Jehovah acknowledges Zion as belonging to him. Today, the Israel of God is thrilled to be the object of Jehovah’s delight in this way, and the other sheep rejoice with them.
