'Alone' in the Bible

I am not able to carry all these people along alone; they are too heavy for me.

I will come down and speak with you there; I will take away from the spirit that [is] on you, and I will place [it] on them; and they will bear the burdens of the people with you; you will not bear it alone.

Because from the top of [the] rocks I see him, from hilltops I watch him. Behold, a people [who] dwell alone, they do not consider themselves among the nations.
