1 Samuel 7:1 - Wesley's Explanatory Notes

Fetch up — That is, by the priests appointed to that work. Hill — This place they chose, both because it was a strong place, where it would be the most safe; and an high place, and therefore visible at some distance, which was convenient for them, who were at that time to direct their prayers and faces towards the ark. And for the same reason David afterwards placed it in the hill of Sion. Sanctified Eleazar — Not that they made him either Levite or Priest; for in Israel persons were not made but born such; but they devoted, or set him apart wholly to attend upon this work. His son — Him they chose rather than his father, because he was younger and stronger, and probably freed from domestic cares, which might divert him from, or disturb him in this work. To keep the ark — To keep the place where it was, clean, and to guard it that none might touch it, but such as God allowed to do so.
