2 verses in the King James Version. Word study for “only” →
You only have I known of all the families of the earth: therefore I will punish you for all your iniquities.
And I will turn your feasts into mourning, and all your songs into lamentation; and I will bring up sackcloth upon all loins, and baldness upon every head; and I will make it as the mourning of an only son , and the end thereof as a bitter day.
