John Gill's Exposition of the Whole Bible
Proverbs 23:1
When thou sittest to eat with a ruler,.... Either a supreme ruler, a king, or a subordinate ruler, a nobleman, a judge, a civil magistrate, a person of honour, dignity, and authority; and to sit at table with such is sometimes allowed, and is always reckoned an honour; this particularly diligent and industrious persons are admitted to, who not only are brought to stand before kings and great persons, but to sit at table with them, and eat food with them. And now the wise man advises such how to behave themselves when this is the case:
consider diligently what [is] before thee; or, "considering consider" q: take special notice of the food and drink set upon the table, and consider well which may be most proper and safe to eat and drink of; for though a man may lawfully eat of whatsoever is set before him; every creature of God being good, if it be received with thanksgiving, and sanctified by the word of God and prayer; yet it is a piece of wisdom to make use of that which is most conducive to health, and less ensnaring; and to observe moderation in all, and not indulge to gluttony and drunkenness: and he should consider also who is before him, which sense the words wilt bear; the ruler that has invited him, and sits at the table with him, and take care that he says or does nothing that may give him offence; and also the noble personages that are guests with him, and behave towards them suitably to their rank and dignity; observe their words and conduct, and imitate the same; yea, even he should consider the servants and waiters that attend, lest, behaving in an indecent and disorderly manner, they should report it to his disadvantage to their ruler or others. But how much greater an honour is it to sit at table with the King of kings, and with his princes, and sup with him! when it becomes the saints, who have this honour, to consider what is set before them; the richest dainties, a feast of things, the body and blood of Christ, which should he spiritually discerned by faith; and not the elements of bread and wine only: likewise the persons before whom they are should be considered; Christ, who sits at his table, and the princes of his people with him; and therefore should not feed without fear, and in a disorderly and indecent manner, as the Corinthians are charged, but with all reverence and humility.
