'Oh' in the Bible

And Abraham said to God, “Oh, that Ishmael [my firstborn] might live before You!”

Then Abraham said [to Him], “Oh, may the Lord not be angry, and I will speak; suppose thirty [righteous people] are found there?” And He said, “I will not do it if I find thirty there.”

Then Abraham said, “Oh may the Lord not be angry [with me], and I will speak only this once; suppose ten [righteous people] are found there?” And He said, “I will not destroy it for the sake of the ten.”

But Lot said to them, “Oh no, [not that place] my lords!

Now look, this town [in the distance] is near enough for us to flee to, and it is small [with only a few people]. Please, let me escape there (is it not small?) so that my life will be saved.”
