C. F. Keil and Franz Delitzsch on 1 Samuel 9:11-12

1Sa 9:11-12

As they were going up to the high place of the town, they met maidens coming out of the town to draw water; and on asking them whether the seer was there, they received this answer: “Yes; behold, he is before thee: make haste, now, for he has come into the town to-day; for the people have a sacrifice to-day upon the high place.” Bamah (in the singular) does not mean the height or hill generally; but throughout it signifies the high place, as a place of sacrifice or prayer.
