Jeremiah 29:14
14
And I have been found of you -- an affirmation of Jehovah; and I have turned back [to] your captivity, and have gathered you out of all the nations, and out of all the places whither I have driven you -- an affirmation of Jehovah -- and I have brought you back unto the place whence I removed you.
Name known only to Himself
In Revelation 19:12, this symbolically means that what the Word is like in its spiritual and celestial senses, no one sees but the Lord, and the person to whom He reveals it. (Apocalypse Revealed 824)
