From the wicked and antichristian party the prophet is bid to turn to the professors of the true religion, and openly, boldly, and sharply, reprove them for their sins, particularly their hypocrisy and formality in worship, Isa 58:1, who yet were angry, and complained that the Lord took no notice of their religious services, particularly their fasting, which is put for the whole; the reason of which was, because they did not fast aright; it was attended with much cruelty, strife, and wickedness, and only lay in external appearances, Isa 58:3, when they are directed how to keep a fast, and are shown what a true fast is, and what works and services are acceptable to God, Isa 58:6 on doing of which, light, health, prosperity, and hearing of their prayers, are promised, provided the yoke of oppression is taken away, and compassion shown to the poor, Isa 58:8, yea, a very fruitful and flourishing estate of the soul is promised, and a rebuilding of waste places, delight in the Lord, and great honour and dignity; so be it that the sabbath of the Lord, or public worship, is attended to in a proper manner, Isa 58:11.
Ver. 1. Cry aloud, spare not, lift up thy voice like a trumpet,.... These words are directed to the prophet; and so the Targum expresses it,"O prophet, cry with thy throat;''and so it is in the original, "cry with the throat" , which is an instrument of speech; and it denotes a loud, strong, vehement cry, when a man exerts his voice, and as it were rends his throat, that he may be heard; as well as it shows the intenseness of his spirit, and the vehemence of his affections, and the importance of what he delivers; and this the prophet is encouraged to do, and "spare not", the voice, throat, or his lungs, nor the people neither he was sent unto; or, "cease not", as the Targum, refrain not from speaking, "cease not crying"; so Ben Melech: "lift up thy voice like a trumpet"; like the voice or sound of a trumpet, which is heard afar, and gives an alarm; and to which the Gospel ministry is sometimes compared, Isa 27:13 all which shows the manner in which the ministers of the word should deliver it, publicly, boldly, with ardour and affection; and also the deafness and stupidity of the people which require it:and show my people their transgression, and the house of Jacob their sins; by whom are meant the professing people of God, the present reformed churches, as distinguished from the antichristian ones, spoken of in the preceding chapter; who yet are guilty of many sins and transgressions, which must be showed them, and they must be sharply reproved for; and particularly their coldness and deadness, formality and hypocrisy in religious worship; their "works not being perfect" before God, or sincere and upright, as is said of the Sardian church, which designs the same persons, Re 3:1.
In the Talmud the words are thus paraphrased, "shew my people their transgression"; these are the disciples of the wise men, whose sins of error or ignorance become to them presumptuous ones; "and the house of Jacob their sins"; these are the people of the earth, or the common people, whose presumptuous sins become to them as sins of ignorance.
