Charles Ellicott Commentary 1 Samuel 25:20

"And it was so, as she rode on her ass, and came down by the covert of the mountain, that, behold, David and his men came down toward her; and she met them." — 1 Samuel 25:20 (ASV)

The covert of the hill.—Keil explains the words sether hahar—literally, a hidden part of the mountain—as probably signifying a hollow between two peaks of the mountain; thus each of the advancing parties would “come down”—Abigail, who approached on one side, and David, who came on the other—and would meet in the hollow between.
