KJV
But Absalom fled. And the young man that
kept the watch lifted up his eyes, and looked, and, behold, there came much
people by the way of the hill side behind him.
BSB
Meanwhile, Absalom had fled. When the young man standing watch looked up, he saw many people coming down the road west of him, along the side of the hill. And the watchman went and reported to the king, “I see men coming from the direction of Horonaim, along the side of the hill.”
