Figuratively, Jericho is taken to be the world, into which Christ came down. They who are in Jericho, know not how to escape from the wisdom of the world, unless they see not Jesus only coming out of Jericho, but also His disciples. This when they saw, great multitudes followed Him, despising the world and all worldly things, that under His guidance they may go up to the heavenly Jerusalem.
The two blind men we may call Judah and Israel, who before the coming of Christ were blind, not seeing the true word which was in the Law and the Prophets, yet sitting by the wayside of the Law and the Prophets, and understanding Him only as after the flesh, they cried to Him who was made of the seed of David according to the flesh.
