Isaiah 5:12

“And the harp, and the viol, the tabret, and pipe, &c.] Instruments of music; some struck with a bow or quill, or touched with the fingers; and others blown with the mouth: and wine are in their feasts; so that they lived jovially and merrily, like sons of Bacchus, more than like the people of God: but they regard not the work of the Lord, neither consider the operation of his hands; meaning not the law, as the Targum and Kimchi, which was the work of the Lord, and the writing of his hands; rather, as Aben Ezra, the punishment inflicted on the ten tribes being carried into captivity; or else the works of creation and providence, and the daily mercies of life; or, best of all, the great work…”

“Music was common at ancient feasts (Isa 24:8-9; Amo 6:5-6). viol--an instrument with twelve strings [JOSEPHUS, Antiquities, 8.10]. tabret--Hebrew, toph, from the use of which in drowning the cries of children sacrificed to Moloch, Tophet received its name. Arabic, duf. A kettle drum, or tambourine. pipe--flute or flageolet: from a Hebrew root "to bore through"; or else, "to dance" (compare Job 21:11-15). regard not . . . Lord--a frequent effect of feasting (Job 1:5; Psa 28:5). work . . . operation--in punishing the guilty (Isa 5:19; Isa 10:12).”

“The prophet proceeds to state still further the extent of their crimes. This verse contains an account of their dissipated habits, and their consequent forgetfulness of God. That they commonly had musical instruments in their feasts, is evident from many passages of the Old Testament; see Amos 6:5-6. Their feasts, also, were attended with songs; Isaiah 24:8-9. The harp - - כנור kinnôr. This is a well-known stringed instrument, employed commonly in sacred music. It is often mentioned as having been used to express the pious feelings of David; Psalms 32:2; Psalms 43:4; Psalms 49:5. It is early mentioned as having been invented by Jubal; Genesis 4:21. It is supposed usually to have had ten…”

“The harp - They give up themselves wholly to luxury. The work - What God hath lately done, and is yet doing, and about to do among them; his grievous judgments, partly inflicted, and partly threatened, which required another course of life. Isaiah 5:13”

“5:12 Self-indulgent and contented, these people never think about the Lord. They were too busy enjoying their drunken parties to reflect on why things went bad in the first place, such as why God sent no rain, or why they lost a battle.”

“the harp: Isa 22:13; Gen 31:27; Job 21:11-14; Dan 5:1-4, Dan 5:23; Amo 6:4-6; Luk 16:19; Jde 1:12 they regard: Isa 5:19; Job 34:27; Psa 28:5, Psa 92:5, Psa 92:6; Hos 4:10, Hos 4:11 Isaiah 5:13”

“Isa 5:12 describes how they go on in their blindness with music and carousing: "And guitar and harp, kettle-drum, and flute, and wine, is their feast; but they regard not the work of Jehovah, and see not the purpose of His hands." "Their feast" is so and so (משׁתּיהם is only a plural in appearance; it is really a singular, as in Dan 1:10, Dan 1:16, and many other passages, with the Yod of the primary form, משׁתּי = משׁתּה, softened: see the remarks on עלה at Isa 1:30, and עשׂיה at Isa 22:11); that is to say, their feast consisted or was composed of exciting music and wine. Knobel construes it, "and there are guitar, etc., and wine is their drink;" but a divided sentence of this kind is very…”
