That walk to go down into Egypt,.... That walk out of their own land to go thither; who sent messengers thither to form an alliance, and get help and assistance, or went in person, to secure themselves from present danger.
Jarchi refers this to the times of Hoshea, the son of Elah, king of Israel, who sent messengers to So, king of Egypt, 2Ki 17:4. Jerom to the times of Jeremiah, to the history in his prophecy, Jer 41:17 and others to Zedekiah.
