Upon Mount Zion shall be deliverance.

Gen 19:17 And it came to pass, when they had brought them forth abroad, that he said, Escape for thy life; look not behind thee, neither stay thou in all the plain; escape to the mountain, lest thou be consumed.
The warning is don't stay in the plain(the plain is full of crowd living in d sin and iniquity)... Destruction is coming upon the world escape to the mountain
Oba 1:17 But upon mount Zion shall be deliverance, and there shall be holiness; and the house of Jacob shall possess their possessions.
