John Lightfoot on Luke 2:44

[They went a day's journey.] The first ordinary day's journey from Jerusalem towards Galilee, was to Neapolis, of old called Sychem, distant thirty miles. But was this the day's journey that Joseph and the company that travelled along wit him made at this time? The place where Christ was first missed by his parents is commonly shewed at this day to travellers, much nearer Jerusalem, by the name of Beere, but ten miles from that city. You may believe those that shew it, as you think fit.
