At that time I will change the speech of the peoples to a pure speech, that all of them may call on the name of the Lord and serve him with one accord.
From beyond the rivers of Ethiopia my suppliants, my scattered ones, shall bring my offering.
References for Zephaniah 3:10
On that day you shall not be put to shame because of all the deeds by which you have rebelled against me; for then I will remove from your midst your proudly exultant ones, and you shall no longer be haughty in my holy mountain.
For I will leave in the midst of you a people humble and lowly. They shall seek refuge in the name of the Lord—
the remnant of Israel; they shall do no wrong and utter no lies, nor shall a deceitful tongue be found in their mouths. Then they will pasture and lie down, and no one shall make them afraid.
