It was so, just as she rode on her donkey and came down under the cover of the mountain, that behold, David and his men came down toward her, and she met them. Bible other translations

“just as she rode.” God’s invisible hand is at work to bless both Abigail and David.

“under the cover of the mountain.” Abigail used the mountain in her area to get the supplies to David without being seen by her husband or the people who would report to him.
