'Bread and Water' in the Bible

You shall serve [only] the Lord your God, and He shall bless your bread and water. I will also remove sickness from among you.

for when Jezebel destroyed the prophets of the Lord, Obadiah took a hundred prophets and hid them by fifties in a cave, and provided them with bread and water.)

Has it not been told to my lord [Elijah] what I did when Jezebel killed the prophets of the Lord, how I hid a hundred of the Lord’s prophets by fifties in a cave, and provided them with bread and water?

and say, ‘Thus says the king, “Put this man in prison, and feed him sparingly with the bread and water until I return safely.”’”

Elisha answered, “You shall not kill them. Would you kill those you have taken captive with your sword and bow? Serve them bread and water, so that they may eat and drink, and go back to their master [King Ben-hadad].”

and say, ‘Thus says the king: “Put this man in prison and feed him just enough bread and water to survive until I return in peace (safely).”’”

because bread and water will be scarce; and they will look at one another in dismay and waste away [in punishment] for their wickedness.
