Ісая 58:3

There follow now the words of the work-righteous themselves, who hold up their fasting before the eyes of God, and complain that He takes no notice of it. And how could He?! "'Wherefore do we fast and Thou seest not, afflict our soul and Thou regardest not?' Behold, on the day of your fasting ye carry on your business, and ye oppress all your labourers. Behold, ye fast with strife and quarrelling, and with smiting with the fist maliciously closed: ye do not fast now to make your voice audible on high." By the side of צוּם (root צם, to press, tie up, constrain) we have here the older expression found in the Pentateuch, נפשׁ ענּה, to do violence to the natural life. In addition to the fasting on the day of atonement (the tenth of the seventh month Tizri), the only fast prescribed by the law, other fasts were observed according to Zac 7:3; Zac 8:19, viz., fasts to commemorate the commencement of the siege of Jerusalem (10th Tebeth), its capture (17th Tammuz), its destruction (9th Aibb), and the murder of Gedaliah (3rd Tizri). The exiles boast of this fasting here; but it is a heartless, dead work, and therefore worthless in the sight of God. There is the most glaring contrast between the object of the fast and their conduct on the fast-day: for they carry on their work-day occupation; they are then, more than at any other time, true taskmasters to their work-people (lest the service of the master should suffer form the service of God); and because when fasting they are doubly irritable and ill-tempered, this leads to quarrelling and strife, and even to striking with angry fist (בּאגרף, from גּרף, to collect together, make into a ball, clench). Hence in their present state the true purpose of fasting is quite unknown to them, viz., to enable them to draw near with importuna…

Here we have, I. The displeasure which these hypocrites conceived against God for not accepting the services which they themselves had a mighty opinion of (Isa 58:3): Wherefore have we fasted, say they, and thou seest not? Thus they went in the way of Cain, who was angry at God, and resented it as a gross affront that his offering was not accepted. Having gone about to put a cheat upon God by their external services, here they go about to pick a quarrel with God for not being pleased with their services, as if he had not done fairly or justly by them. Observe, 1. How they boast of themselves, and magnify their own performances: "We have fasted, and afflicted our souls; we have not only sought God daily (Isa 58:2), but have kept some certain times of more solemn devotion." Some think this refers to the yearly fast (which was called the day of atonement), others to their arbitrary occasional fasts. Note, It is common for unhumbled hearts to be proud of their professions of humiliation, as the Pharisee (Luk 18:12), I fast twice in the week. 2. What they expected from their performances. They thought God should take great notice of them, and own himself a debtor to them for their services. Note, It is a common thing for hypocrites, while they perform the external services of religion, to promise themselves that acceptance with God which he has promised only to the sincere; as if they must be accepted of course, or for a compliment. 3. How heinously they take it that God had not put some particular marks of his favour upon them, that he had not immediately delivered them out of their troubles and advanced them to honour and prosperity. They charge God with injustice and partiality, and seem resolved to throw up their religion, and justify themselves in doing so with this, th…

58:3 Fasting should be a time of self-deprivation in order to focus on God and pleasing him (Lev 16:29; see Zech 7:5). However, these people were only interested in pleasing themselves and continuing in their sins.
