Joel 2:31-32

Expanded Bible

³¹ The sun will ·become dark [turn to darkness],
    the moon ·red as blood [^Lto blood; Rev. 6:12],
    before the ·overwhelming [great] and ·terrible [awesome] day of the Lord comes.
³² ·Then [^LAnd it will happen that] ·anyone [all] who calls on the [^Lname of the] Lord
    will be ·saved [rescued],
because on Mount Zion and in Jerusalem
    there will be people who will ·be saved [escape; be delivered],
just as the Lord has said.
·Those left alive after the day of punishment [The remnant/survivors]
are the people whom the Lord called.
