Genesis 28:12

This ladder may be considered, either,

1. Literally, and so it represented to Jacob the providence of God, who, though he dwell in heaven, extends his care and government to the earth, and particularly makes use of the angels as ministering spirits for the good of his people. And these angels do not appear idle, or standing still, but always in motion, either ascending to God to receive his commands, or descending to earth for the execution of them. Which was a most seasonable vision for Jacob in his sad and sorrowful condition, that he might see that though he was forsaken and persecuted by men, and forced to flee away secretly for fear of his life, yet he neither was, nor should be, neglected or forsaken by God in this whole journey.
