'Alone' in the Bible

Then David said to Abishai and to all his servants, “Look, my son [Absalom] who came from my own body, is seeking my life; how much more [reason] now [does] this Benjamite [have to curse me]? Let him alone and let him curse, for [it could be that] the Lord has told him [to do it].

I will strike while he is weary and exhausted, and terrify him; and all the people with him will flee [in terror]. Then I will attack the king alone,

Now David was sitting between the two gates; and the lookout went up to the roof of the gate by the wall, and when he raised his eyes and looked, he saw a man running alone.

The lookout called down and told the king. The king said, “If he is alone, he has good news to tell.” And he came nearer and nearer.

Then the lookout saw another man running, and he called to the gatekeeper and said, “Look, another man running alone.” The king said, “He also is bringing good news.”
