'Alone' in the Bible

{And in that} they said to leave alone the stump of the tree's root, so your kingdom [will be] restored for you {when} you acknowledge that heaven [is] sovereign.

And I saw, I, Daniel {alone}, the vision; and the people who were with me {did not see} the vision; nevertheless, a great trembling fell upon them and they fled [in order] to hide themselves.

And I myself, Daniel, alone saw this great vision, and [as a result] {no strength was left in me} and {my complexion grew deathly pale}, and I did not retain any strength.

And also their gods with their idols [and] with the {precious vessels}, silver and gold he will take to Egypt into captivity, and [for] years {he will leave the king of the north alone}.
