Upon his bed - That is, “upon his couch.” The Jews, like other Orientals, reclined upon couches at their meals (Amos 6:4; Ezekiel 23:41, etc.). Ahab turns his face toward the back of the couch, rejecting all converse with others, and so remains, after the banquet is served, refusing to partake of it. Such an open manifestation of ill temper is thoroughly characteristic of an Oriental king.

4 And Ahab came into his house heavy and displeased because of the word which Naboth the Jezreelite had spoken to him: for he had said, I will not give thee the inheritance of my fathers. And he laid him down upon his bed, and turned away his face, and would eat no bread.
