'Alone' in the Bible

I am not able to carry all these people alone, because the burden is too heavy for me.

Then I will come down and speak with you there, and I will take away some of the Spirit who is upon you, and will put Him upon them; and they shall bear the burden of the people with you, so that you will not have to bear it all alone.

“For from the top of the rocks I see Israel,And from the hills I look at him.Behold, the people [of Israel] shall dwell aloneAnd will not be reckoned among the nations.
