Genesis 21:14

“And Abraham rose up early in the morning, etc.] It was in the night the Lord spoke to him, and bid him hearken to the voice of Sarah; and, as soon as it was morning, he arose, and was not disobedient to the heavenly vision; for, though the thing he was directed to was disagreeable to flesh and blood, and contrary to his natural affection, yet, it being the will of God, he readily complied with it: and took bread and a bottle of water; a loaf of bread very probably, and a leathern or wooden bottle of water, as Aben Ezra supposes it to be; for there is no need to say that these are put for all necessaries, and a liberal provision that might be made by Abraham; but it is to be taken strictly,…”
