'Alone' in the Bible

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

And I will come down and talk with thee there: and I will take of the Spirit which is upon thee, and will put it upon them; and they shall bear the burden of the people with thee, that thou bear it not thyself alone.

For from the top of the rocks I see him, And from the hills I behold him: lo, it is a people that dwelleth alone, And shall not be reckoned among the nations.
