g13:18 Or “has lifted up his heel against me.” The Greek text preserves the idiom of Ps. 41:9, which speaks of a treacherous betrayal. In the Semitic culture it is the greatest breach of etiquette to sit and eat with a friend and then later betray them. This is why many would never eat with someone they were not on good terms with. See also footnotes on Ps. 41:9.
