Matthew 23:37 (a) The Lord JESUS compares Himself to a mother hen and the individual Israelite to the baby chicken whom He desired to protect, preserve and provide with every need. In Luke 13:34, where the word "brood" is used instead of the word "chickens," we learn that in the early part of His ministry, CHRIST intended to gather all of Israel under His wings. However, toward the end of His ministry, as we find it in Matthew, He called individual Israelites to come to Him for protection, for in the meanwhile, the nation had rejected Him as their Lord, their King, and their Messiah. No longer does He endeavor to call the whole nation to Him, but now calls individual persons.
