Isaiah 62:6-8

Amplified Bible

⁶ 
On your walls, O Jerusalem, I have appointed and stationed watchmen (prophets),
Who will never keep silent day or night;
You who profess the Lord, take no rest for yourselves,
⁷ 
And give Him no rest [from your prayers] until He establishes Jerusalem
And makes her a praise on the earth.
⁸ 
The Lord has sworn [an oath] by His right hand and by His mighty arm,
“I will never again give your grain as food for your enemies,
Nor will [the invading] foreigners drink your new wine for which you have labored.”
