'Oh' in the Bible

My soul, my soul! I am in anguish! Oh, my heart!My heart is pounding in me;I cannot be silent,Because you have heard, O my soul,The sound of the trumpet,The alarm of war.

Oh that my head were watersAnd my eyes a fountain of tears,That I might weep day and nightFor the slain of the daughter of my people!

So now then, speak to the men of Judah and against the inhabitants of Jerusalem saying, ‘Thus says the Lord, “Behold, I am fashioning calamity against you and devising a plan against you. Oh turn back, each of you from his evil way, and reform your ways and your deeds.”’

Yet I sent you all My servants the prophets, again and again, saying, “Oh, do not do this abominable thing which I hate.”
