“Then I proclaimed a fast there, at the river of Ahava, that we might afflict ourselves before our God, to seek of Him a right way for us, and for our little ones, and for all our substance.
For I was ashamed to require of the king a band of soldiers and horsemen to help us against the enemy in the way: because we had spoken unto the king, saying, ‘The hand of our God is upon all them for good that seek Him; but His power and His wrath is against all them that forsake Him.’
So we fasted and besought our God for this: and He was intreated of us.”  Ezra 8:21-23  (KJB)
