“Put a knife to your throat”
When you sit down to dine with a ruler, consider carefully what is set before you, and put a knife to your throat if you possess a great appetite. (Proverbs 23:1–2 BSB)
What it sounds like today
A violent, alarming instruction about a knife.
The cultural key
Taken literally this is shocking advice; as an idiom it is vivid coaching in self-restraint. When invited to 'dine with a ruler,' a person of appetite might gorge on the delicacies and let his hunger master him, either making a fool of himself before a powerful man or falling under obligation to a calculating host. The proverb says: rein yourself in so completely that it is as though a knife were held to your throat, ready to check the first greedy move. The next line explains the danger, 'do not crave his delicacies, for that food is deceptive,' the meal may be bait, a display of favor that binds you to the ruler or exposes your lack of discipline. It belongs with the counsel not to push yourself forward in a king's presence (Proverbs 25:6). Far from endorsing violence, it is a memorable picture of mastering one's appetites in a setting where losing control is costly.
Recovered meaning
'Put a knife to your throat' is a stark idiom for radical self-control at a powerful host's table: check your appetite completely, because the lavish food is a snare that can shame you or put you in his debt.
