Matthew Poole and continuators on 1 Samuel 13:11

11 ¶ And Samuel said, What hast thou done ? And Saul said, Because I saw that the people were scattered from me, and that thou camest not within the days appointed , and that the Philistines gathered themselves together to Michmash:

He suspected that Saul had transgressed; either by his dejected countenance, or some words uttered by him, though not here expressed: but he asks him, that he might be more fully and certainly informed, and that Saul might be brought to an ingenuous Confession of his Sin, and true Repentance for it.

i. e. When the seventh day was come, and a good part of it past, whence I concluded thou wouldst not come that day, and that thou hadst forgotten thy appointment, or been hindred by some extraordinary occasion.
