Joel 2:10-11 (ESV Strong's)
10 The earth quakes before them;
the heavens tremble.
The sun and the moon are darkened,
and the stars withdraw their shining.
11 The Lord utters his voice
before his army,
for his camp is exceedingly great;
he who executes his word is powerful.
For the day of the Lord is great and very awesome;
who can endure it?
He who provided the lights in heaven will withdraw the knowledge and order they give as heaven and earth shake on that day. The Lord will be true to His word and render the consequences He promised for disobedience. He utters His voice before the invading arm coming to Zion to execute His judgement.
