The fast that God chooses
"Is not this the fast that I have chosen? to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke? Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh?" Isaiah 58:6-7
The people Isaiah is addressing do fast. A great deal. And they complain about it: why have we fasted, and thou seest not? God's answer takes up the whole chapter, and it is severe: they fast while continuing to exploit their workers.
What must be heard is that God does not tell them to stop fasting. He redefines what the word covers. The fast He chooses has two movements, and the text puts them in this order.
First, undo. Loose, undo, let go free, break. Four verbs of release, and every one of them is transitive: they act on somebody else. The first work of a fast is not to deprive yourself, it is to let go of what you are holding. A debt you could cancel. An employee you underpay. A grudge you keep on a leash.
Then, give. Deal your bread, bring the poor into your house, cover the naked. Notice how physical it is, and how domestic — "bring the poor that are cast out to thy house." This is not a policy programme. This is your front door.
And the last line closes it all: "hide not thyself from thine own flesh." The Hebrew says exactly that — your own flesh. The hungry man is not a case; he is someone of the same flesh as you. The biblical fast is the deprivation that makes that kinship physically real to you.
None of this cancels the fast from food. Not eating remains a school: hunger recalls the hunger of others, and the body learns it is not in charge. But if the empty stomach never opens a hand, Isaiah says God is not looking at it.
Next time you fast. Decide in advance what this fast is going to release for somebody else. A debt, a wage, a door, a pardon. Write it down before you begin — otherwise, on the day, you will be hungry and you will have forgotten.
