'Alone' in the Bible

I did not sit in the circle of merrymakers,Nor did I exult.Because of Your hand upon me I sat alone,For You filled me with indignation.

when the army of the king of Babylon was fighting against Jerusalem and against all the remaining cities of Judah, that is, Lachish and Azekah, for they alone remained as fortified cities among the cities of Judah.

“Arise, go up against a nation which is at ease,Which lives securely,” declares the Lord.“It has no gates or bars;They dwell alone.
