'Appointment' in the Bible

Saul waited seven days for the appointment set by Samuel. When Samuel did not arrive at Gilgal, as the people began to scatter from Saul,

and Samuel saith, 'What hast thou done?' And Saul saith, 'Because I saw that the people were scattered from off me, and thou hadst not come at the appointment of the days, and the Philistines are gathered to Michmash,

In the morning Jonathan, accompanied by a servant, went out to the field for the appointment with David.
