John 13:2 - 15

It was the season of rain at the time of the Last Supper and since the streets in Jerusalem were not hard, it would become miry and unclean. In addition to this, the people in the Middle East were accustomed to wearing only sandals, which easily made their feet dirty.   Jesus therefore insisted that the feet of the disciples be washed before entering the Upper Room.

Elijah the Tishbite from Gilead is first mentioned in 1 Kings Chapter 17 without any background information of him. When the people of Israel gave the glory  to Baal (the god of rain) for the fertility of the land, his zeal for Yahweh made him challenge King Ahab, that there would be no rain in Israel till he brings the word again(1 kings 17:1).
