Kitzur Ba'al HaTurim on Genesis 28:11

ויפגע במקום ג"פ כתיב מקום בפסוק רמז לג' רגלים שיעלו בניו למקום ההוא: And he arrived at the place – the word place is used three times in this verse, which is a hint to the three pilgrimage holy days on which his children would come up to that place in the future (see Chullin 91b)
