Jonah 3

Do you remember a second chance in life? Do you remember the first? After hearing the word of God a second time, Jonah makes his journey to Nineveh and proclaims Gods word. As a result, the people repent and fast. Just the same, the king casts aside his robe (authority, duties and responsibilities) to consecrate himself as well.

It's one thing for the people of the land to fast. It's another when designated and/or appointed leaders and the word is proclaimed.

Isaiah 58:6-8
