1 Samuel 28:20-24

Then Saul immediately fell full length to the ground and was very afraid because of Samuel’s words; there was no strength in him either, because he had eaten no food all day and all night.

The woman came to Saul and saw that he was utterly horrified, and she said to him, “Behold, your servant has obeyed you, and I have taken my life in my hand and have listened to your words which you spoke to me.

So now you too, please listen to the voice of your servant, and let me serve you a piece of bread, and eat it, so that you will have strength when you go on your way.”

But he refused and said, “I will not eat.” However, his servants together with the woman urged him, and he listened to them. So he got up from the ground and sat on the bed.

Now the woman had a fattened calf in the house, and she quickly slaughtered it; then she took flour, kneaded it and baked unleavened bread from it.
