Isaiah 58:5

Amplified Bible

⁵ 
“Is a fast such as this what I have chosen, a day for a man to humble himself [with sorrow in his soul]?
Is it only to bow down his head like a reed
And to make sackcloth and ashes as a bed [pretending to have a repentant heart]?
Do you call this a fast and a day pleasing to the Lord?
