THE HOLY TRINITY (or THE HOSPITALITY OF ABRAHAM AND SARA).

The Old Testament, book of Genesis:

"Yahweh appeared to him at the Oak of Mamre while he was sitting by the entrance of the tent during the hottest part of the day. He looked up, and there he saw three men standing near him. As soon he saw them he ran from the entrance of the tent to meet them, and bowed to the ground. ' My Lord', he said, 'I beg you, if I find favour with you, kindly do not pass your servant by. A little water shall be brought; you shall wash your feet and lie down under the tree. Let me fetch a little bread and you shall refresh yourselves before going further. That is why you have come in your servant's direction.' They replied, 'Do as you say.' Abraham hastened to the tent to find Sarah. 'Hurry', he said 'knead three bushels of flour and make loaves.' Then running to the cattle Abraham took a fine and tender calf and gave it to the servant, who hurried to prepare it. Then taking cream, milk and the calf he had prepared, he laid all before them, and they ate while he remained standing near them under the tree."
