Isaiah 58:5

Amplified Bible, Classic Edition

⁵ Is such a fast as yours what I have chosen, a day for a man to humble himself with sorrow in his soul? [Is true fasting merely mechanical?] Is it only to bow down his head like a bulrush and to spread sackcloth and ashes under him [to indicate a condition of heart that he does not have]? Will you call this a fast and an acceptable day to the Lord?
