Of him that hath an evil eye - Never eat with a covetous or stingy man; if he entertains you at his own expense, he grudges every morsel you put in your mouth. This is well marked by the wise man in the next verse: "Eat and drink, saith he: but his heart is not with thee."
A different danger from that of Proverbs 23:1. The hazard here is the hospitality of the purse-proud rich, avaricious or grudging even in his banquets.
Evil eye - Not with the later associations of a mysterious power for mischief, but simply, as in the margin ref. and in Matthew 20:15.
