Tumingin siya, at narito, sa may ulunan niya ay may isang tinapay na niluto sa mga baga at isang lalagyan ng tubig. Kumain siya at uminom, at muli siyang humiga.
Rashi
a glowing coal Heb. רִצְפָּה, a coal, and similarly, (I Kings 19:6) “a cake baked on hot coals (עֻגַּת רְצָפִים),” like עֻגַּת רְשָׁפִים. In regards to Isaiah and Elijah, however, it is written with a ‘zadi,’ רִצְפָּה, because they spoke ill of Israel. This one [Isaiah] called them a people of unclean lips, and this one [Elijah] said, (ibid. 10) “For...have forsaken Your covenant.” Said the Holy One, blessed be He, to the angel, “Break the mouth (רְצוֹץ פֶּה) that spoke ill of My children.”
