Isaiah 1:5

“Why should ye be stricken any more? &c.] Or “for what are ye stricken again”f25? with afflictions and chastisements, with which God smites his people by way of correction for their sins, (<235717>Isaiah 57:17 <280601> Hosea 6:1) and the sense is, either that they did not consider what they were afflicted for, that it was for their sins and transgressions; they thought they came by chance, or imputed them to second causes, and so went on in sin, and added sin to sin; to which sense the Targum, Jarchi, and Kimchi, incline: or the meaning is, that the chastisements that were laid upon them were to no purpose; had produced no good effect, were of no avail, and unprofitable to them; and which is…”

“Why--rather, as Vulgate, "On what part." Image from a body covered all over with marks of blows (Psa 38:3). There is no part in which you have not been smitten. head . . . sick, &c.--not referring, as it is commonly quoted, to their sins, but to the universality of their punishment. However, sin, the moral disease of the head or intellect, and the heart, is doubtless made its own punishment (Pro 1:31; Jer 2:19; Hos 8:11). "Sick," literally, "is in a state of sickness" [GESENIUS]; "has passed into sickness" [MAURER].”

“Why ... - The prophet now, by an abrupt change in the discourse, calls their attention to the effects of their sins. Instead of saving that they had been smitten, or of saying that they had been punished for their sins, he assumes both, and asks why it should be repeated. The Vulgate reads this: ‘Super quo - on what part - shall I smite you anymore?’ This expresses well the sense of the Hebrew - על־מה ‛al-meh - upon what; and the meaning is, ‘what part of the body can be found on which blows have not been inflicted? On every part there are traces of the stripes which have been inflicted for your sins.’ The idea is taken from a body that is all covered over with weals or marks of blows, and…”

“Head - The very head and heart of the body politick, from whence the plague is derived to all the other members. Isaiah 1:7”

“1:5 God sent famine, war, disease, and death as punishment. In most cases, however, God wanted to change stubborn behavior rather than simply to punish. • As a result of their persistent rebellion, the people’s head is injured and their heart is sick. The nation was wounded physically from Assyrian aggression, while spiritually they were defiled and overtaken by sin (64:6).”

“should: Isa 9:13, Isa 9:21; Jer 2:30, Jer 5:3, Jer 6:28-30; Eze 24:13; Heb 12:5-8 ye will: Ch2 28:22; Jer 9:3; Rev 16:8-11 revolt more and more: Heb. increase revolt the whole: Isa 1:23; Neh 9:34; Jer 5:5, Jer 5:31; Dan 9:8-11; Zep 3:1-4 Isaiah 1:6”

“In this v. a disputed question arises as to the words על־מה (מה, the shorter, sharper form of מה, which is common even before non-gutturals, Ges. 32, 1): viz., whether they mean "wherefore," as the lxx, Targums, Vulgate, and most of the early versions render them, or "upon what," i.e., upon which part of the body, as others, including Schrring, suppose. Luzzatto maintains that the latter rendering is spiritless, more especially because there is nothing in the fact that a limb has been struck already to prevent its being struck again; but such objections as these can only arise in connection with a purely literal interpretation of the passage. If we adopted this rendering, the real meaning…”
