Psalm 79:10-12

Amplified Bible

¹⁰ 
Why should the [Gentile] nations say, “Where is their God?”
Let there be known [without delay] among the nations in our sight [and to this generation],
Your vengeance for the blood of Your servants which has been poured out.
¹¹ 
Let the groaning and sighing of the prisoner come before You;
According to the greatness of Your power keep safe those who are doomed to die.
¹² 
And return into the lap of our neighbors sevenfold
The taunts with which they have taunted You, O Lord.
