27 When Ahab heard these words, he tore his clothes, put on sackcloth and fasted. He lay in sackcloth and went around meekly.
(Read 1 Kings 21:17-29)
Blessed Paul complains that he was sold under sin, Romans 7:14, as a poor captive against his will; but Ahab was willing, he sold himself to sin; of choice, and as his own act and deed, he loved the dominion of sin. Jezebel his wife stirred him up to do wickedly. Ahab is reproved, and his sin set before his eyes, by Elijah. That man's condition is very miserable, who has made the word of God his enemy; and very desperate, who reckons the ministers of that word his enemies, because they tell him the truth. Ahab put on the garb and guise of a penitent, yet his heart was unhumbled and unchanged. Ahab's repentance was only what might be seen of men; it was outward only. Let this encourage all that truly repent, and unfeignedly believe the holy gospel, that if a pretending partial penitent shall go to his house reprieved, doubtless, a sincere believing penitent shall go to his house justified.
3 In every province to which the edict and order of the king came, there was great mourning among the Jews, with fasting, weeping and wailing. Many lay in sackcloth and ashes.
(Read Esther 4:1-4)
Mordecai avowed his relation to the Jews. Public calamities, that oppress the church of God, should affect our hearts more than any private affliction, and it is peculiarly distressing to occasion sufferings to others. God will keep those that are exposed to evil by the tenderness of their consciences.

Commentary on Matthew 6:16-18
(Read Matthew 6:16-18)
Religious fasting is a duty required of the disciples of Christ, but it is not so much a duty itself, as a means to dispose us for other duties. Fasting is the humbling of the soul, Psalm 35:13; that is the inside of the duty; let that, therefore, be thy principal care, and as to the outside of it, covet not to let it be seen. God sees in secret, and will reward openly.
