'O God' in the Bible

And Gideon said unto God, - If thou art about to bring salvation, by my hand, unto Israel, as thou hast spoken,

Then said Gideon unto God, Let not thine anger kindle upon me, but let me speak, only this once, - Let me, I pray thee, put to the proof, only this once, with the fleece, I pray thee, let it be dry on the fleece alone, while, on all the ground, there be dew.

for lo! thou, art about to conceive and bear a son, and no, razor, shall come on his head, for, one separate unto God, shall the boy be from his birth, - and, he, shall begin to save Israel out of the hand of the Philistines.

But he said unto me, Lo! thou art about to conceive, and bear a son, - now, therefore, do not drink wine or strong drink, nor eat anything unclean, for, one separate unto God, shall the boy be, from his birth until the day of his death.

so he told her all his heart, and said to her - No, razor, hath come on my head, for, one separate unto God, have I been, from my birth, - if I were shaven, then would depart from me my strength, and I should become weak, and be as any other man.

So then Samson cried unto Yahweh, and said, - My Lord Yahweh! remember me, I pray thee, - and strengthen me, I pray thee, only this once, O God, that I may be avenged, with one avenging, for my two eyes, upon the Philistines.
