'Alone' in the Bible

I am not able to bear all this people alone, because it is too heavy for me.

I will come down and talk with you there. I will take of the Spirit which is on you, and will put it on them; and they shall bear the burden of the people with you, that you not bear it yourself alone.

For from the top of the rocks I see him. From the hills I see him. Behold, it is a people that dwells alone, and shall not be reckoned among the nations.
