'Alone' in the Bible

Are there any among the idols of the nations who can send rain?Or can the heavens [of their own will] give showers?Is it not You, O Lord our God?Therefore we will wait and hope [confidently] in You,For You are the one who has made all these things [the heavens and the rain].

I did not sit with the group of those who celebrate,Nor did I rejoice;I sat alone because Your [powerful] hand was upon me,For You had filled me with indignation [at their sin].

“Arise [Nebuchadnezzar], go up against a nation which is at ease,Which lives securely,” says the Lord,“A nation which has neither gates nor bars;They dwell apart and alone.
