The most useful thing about hexagram 5 in practice is the fifth line, which counsels waiting with wine and food, and perseverance bringing good fortune.
That line establishes the hexagram's characteristic advice, which is not endurance but provisioning. The counsel is that during a delay one should eat well, keep company, and maintain ordinary life rather than suspending it until the outcome arrives. A great many querents who draw this figure have put their lives on hold, and the text explicitly tells them not to.
The reading is otherwise straightforward: a situation whose resolution is not in the querent's hands and will not be accelerated by effort. The distinction from other delay hexagrams is that here the outcome is not in doubt, only its timing. What is being waited for is coming.
The top line complicates that. One falls into the pit, three uninvited guests arrive, and honouring them brings good fortune in the end. Nobody agrees on what the three guests are. Wilhelm reads them as unexpected help arriving in unwelcome form; other translations leave the image unexplained, which is probably more honest. It is a good example of a passage where the received interpretation is a commentator's guess repeated until it hardened.
The hexagram inverts to Conflict, and the pair sets waiting against contention, two responses to the same obstruction, placed side by side in the sequence so that each is read against the other. Reading either without its partner loses the comparison the compiler evidently intended.
