ISB ~ Mark 9 v11

first Elijah must come:Elijahs reappearance was a common expectation based on the prophecy of Mal 4:5.

• In context, God promised to send Elijah to prepare Israel for his scheduled arrival on the “day of the Lord”. His mission was to restore family relationships (Mal 4:6) and the tribes of Israel (Sir 48:10). John the Baptist fulfills this prophetic role as the forerunner to Jesus (9:13). See note on Mk 1:6.
