'Cursing' in the Bible

Then one’s uncle, or his undertaker, shall come to bring the [disease-infected] body out of the house, [to cremate it], and he will say to another in the farthest part of the house, “Is there anyone else with you?” And that one will say, “No one.” Then he will respond, “Hush! Keep quiet! For the name of the Lord is not to be mentioned [even casually, for fear that we might invoke even more punishment].”
