Those that are voluptuous and given to appetite (Pro 23:2) are glad to be where there is good cheer stirring, and those that are covetous and saving, that they may spare at home, will be glad to get a dinner at another man's table; and therefore both are here advised not to be forward to accept of every man's invitation, but especially not to thrust themselves in uninvited. Observe, 1. There are those that pretend to bid their friends welcome that are not hearty and sincere in it. They have a fair tongue, and know what they should say: Eat and drink, saith he, because it is expected that the master of the feast should so compliment his guests; but they have an evil eye, and grudge their guests every bit they eat, especially if the eat freely. They would seem to be liberal in making the entertainment, and would have the credit of it, but they have so great a love to their money, and so little to their friends, that they cannot have the comfort of it, nor any enjoyment of themselves or their friends. The miser's feast is his penance. If a man be so very selfish, and sordid, and mean that he cannot find in his heart to bid his friends welcome to what he has, he ought not to add to that the guilt of dissimulation by inviting them, but let him own himself to be what he is, that the vile person may not be called liberal nor the churl bountiful, Isa 32:5. 2. One can have no comfort in accepting the entertainments that are given grudgingly: "Eat not thou the bread of such a man; let him keep it to himself. Do not sponge upon those that are bountiful, nor make thyself burdensome to any; but especially scorn to be beholden to those that are paltry and not sincere. Better have a dinner of herbs, and true welcome, than dainty meats without it. Therefore," (1.) "Judge of the man as his mind is. Thou thinkest to pay thy respect to him as a friend, so thou takest him to be, because he compliments thee, but as he thinks in his heart so is he, not as he speaks with his tongue." We are that really, both to God and man, which we are inwardly; and neither religion nor friendship is worth any thing further than as it is sincere. (2.) "Judge of the meat as the digestion is and as it agrees with thee. He bids thee eat freely, but, first or last, he will discover his sordid covetous humour, and as he thinks in his heart so will he look, and give thee to understand that thou art not welcome, and then the morsel thou hast eaten thou shalt vomit up; the very thought of that will make thee even to vomit the meat thou hast eaten, and eat the words thou has spoken in returning his compliments and giving him thanks for his civilities. Thou shalt lose thy sweet words, which he has given thee and thou has given him."

The morsel which thou hast eaten, shalt thou vomit up,.... It shall turn in thy stomach, thou shall not be able to keep it, when thou understandest thou art not welcome; or thou wilt wish thou hadst never eaten a bit, or that thou couldest vomit up what thou hast; so disagreeable is the thought of being unwelcome, or when this appears to be the case;

and lose thy sweet words; expressed in thankfulness to the master of the feast, in praise of his food, in pleasantry with him, and the other guests at table; all which are repented of when a man finds he is not welcome.

The morsel . . . words--that is, disgusted with his true character, all pleasant intercourse will be destroyed.
