WHAT TO DO DURING THE 3 DAYS OF DARKNESS

YashaYahu 26:20 Go, my people, enter your rooms, and shut your doors behind you; hide yourself, as it were, for a little while, until the displeasure is past. 21 For look, Yahuah is coming out of His place to punish the inhabitants of the arets for their lawlessness. And the arets shall disclose her blood, and no longer cover her slain.
