Joel 2:31-32

Amplified Bible

³¹ 
“The sun will be turned into darkness
And the moon into blood
Before the great and terrible day of the Lord comes.^(A)
32 
“And it shall come about that whoever calls on the name of the Lord
Will be saved [from the coming judgment]
For on Mount Zion and in Jerusalem
There will be those who escape,
As the Lord has said,
Even among the remnant [of survivors] whom the Lord calls.^(B)
