A Stronghold in the Day of Trouble

Nahum 1:7-9 (NKJV)
7 The Lord is good,
A stronghold in the day of trouble;
And He knows those who trust in Him.
8 But with an overflowing flood
He will make an utter end of its place,
And darkness will pursue His enemies.
9 What do you conspire against the Lord?
He will make an utter end of it.
Affliction will not rise up a second time.
