Ezra 8:21-22

²¹Then I proclaimed a fast there, at the river Aha'va, that we might humble ourselves before our God, to seek from him a straight way for ourselves, our children, and all our goods. ²²For I was ashamed to ask the king for a band of soldiers and horsemen to protect us against the enemy on our way; since we had told the king, "The hand of our God is for good upon all that seek him, and the power of his wrath is against all that forsake him."
