Why the King Is Bound Among Israel by Abraham's Running

[(Exodus 27:20:) AND YOU SHALL COMMAND ….] This text is related (to Song of Songs 7:6): YOUR HEAD UPON YOU IS LIKE CARMEL, <AND THE LOCKS (dallah) OF YOUR HEAD (rosh) ARE LIKE PURPLE>. The poor (dallim) and the needy (rashim) who are among you are as dear to Me as Daniel. [(The same verse, continued:) A KING IS BOUND IN THE TROUGHS (rehatim).] The Holy One, blessed be He, said to them: As it were, I am bound among you. By virtue of what? By virtue of the runnings that Abraham ran before Me, as it is said (Genesis 18:6–7): AND ABRAHAM HASTENED INTO THE TENT, <…> AND ABRAHAM RAN UNTO THE HERD. Hence, A KING IS BOUND IN THE TROUGHS (rehatim). Rabbi Levi said: By virtue of Jacob, of whom it is written (Genesis 30:38): <AND HE SET THE RODS> IN THE TROUGHS (rehatim), IN THE WATERING TROUGHS.
