'Oh' in the Bible

Jabez called on the God of Israel, saying, "Oh that you would bless me indeed, and enlarge my border, and that your hand might be with me, and that you would keep me from evil, that it not be to my sorrow!" God granted him that which he requested.

David longed, and said, "Oh that one would give me water to drink of the well of Bethlehem, which is by the gate!"

Oh give thanks to Yahweh. Call on his name. Make his doings known among the peoples.

Oh give thanks to Yahweh, for he is good, for his loving kindness endures forever.
