Jer.4.2

And thou shalt swear, The LORD liveth, in truth, in judgment, and in righteousness; and the nations shall bless themselves in him, and in him shall they glory.

Jer.4.2

Then you can say words like, "As GOD lives... 'and have them mean something true and just and right. And the godless nations will get caught up in the blessing and find something in Israel to write home about." [JC]

Jer.4.2

and if in a truthful, just and righteous way you swear, 'As surely as the LORD lives,' then the nations will be blessed by him and in him they will glory."

Jer.4.2

and if you will swear by my name alone, and begin to live good, honest lives and uphold justice, then you will be a blessing to the nations of the world, and all people will come and praise my name."
