Isaiah 8:19

“And when they shall say unto you, &c.] These are the words of Christ continued, as making his appearance in Israel; and are an address to his people among them, even to his children, disciples, and followers, advising them what they should do, when those among whom they dwelt should press them to seek unto them that have familiar spirits, and unto wizards, that peep, and that mutter; meaning the Scribes and Pharisees, the doctors among the Jews, who sat in Moses’s chair, and who were very much given to sorcery, and the magic art, and used enchantments, which were performed by “muttering”; hence we read of muttering over a wound for the healing of it; and muttering over serpents and scorpions…”

“Seek unto--Consult in your national difficulties. them . . . familiar spirits--necromancers, spirit charmers. So Saul, when he had forsaken God (Sa1 28:7, &c.), consulted the witch of En-dor in his difficulties. These follow in the wake of idolatry, which prevailed under Ahaz (Kg2 16:3-4, Kg2 16:10). He copied the soothsaying as he did the idolatrous "altar" of Damascus (compare Lev 20:6, which forbids it, Isa 19:3). wizards--men claiming supernatural knowledge; from the old English, "to wit," that is, know. peep--rather "chirp faintly," as young birds do; this sound was generally ascribed to departed spirits; by ventriloquism the soothsayers caused a low sound to proceed as from a grave, or…”

“And when they shall say - When the people, instead of putting confidence in God, shall propose to apply to necromancers. In the time of Ahaz the people were, as they were often, much inclined to idolatry; 2 Kings 16:10. In their troubles and embarrassments, instead of looking to Yahweh, they imitated the example of surrounding nations, and applied for relief to those who professed to be able to hold converse with spirits. That it was common for idolatrous people to seek direction from those who professed that they had the power of divining, is well known; see Isaiah 19:3; Isaiah 29:4. It was expressly forbidden to the Jews to have recourse to those who made such professions; Leviticus 20:6;…”

“And when they - The Israelites, who are fallen from God, into superstition and idolatry. You - My children, whom the prophet arms against the common temptation. Mutter - That speak with a low voice, as these two words signify, which they affected to do, speaking rather inwardly in their bellies, than audibly with their mouths. Should not - This answer the prophet puts into their mouths, doth not every nation, in cases of difficulty, seek to their gods? Much more should we do so, that have the only true God for our God. For the living - That is, for living men to enquire of the living God, is proper and reasonable; but it is highly absurd for them to forsake him, and to seek dead idols,…”

“8:19-22 Isaiah contrasts his counsel with that of his ungodly contemporaries. Isaiah’s message gives light, whereas the message of the spiritists led to darkness and death. • Mediums used various means of divination, including summoning the dead, in the attempt to determine the future (see 19:3). God had banned these useless activities (47:9; Deut 18:9-11).”

“Seek: Isa 19:3; Lev 20:6; Deu 18:11; Sa1 28:8; Ch1 10:13; Ch2 33:6 that peep: Isa 29:4 should not: Sa1 28:16; Kg2 1:3; Pe2 2:1 for the living: Psa 106:28; Jer 10:10; Th1 1:9 Isaiah 8:20”

“It is to this ecclesiola in ecclesia that the prophet's admonition is addressed. "And when they shall say to you, Inquire of the necromancers, and of the soothsayers that chirp and whisper:-Should not a people inquire of its God? for the living to the dead?" The appeal is supposed to be made by Judaeans of the existing stamp; for we know from Isa 2:6; Isa 3:2-3, that all kinds of heathen superstitions had found their way into Jerusalem, and were practised there as a trade. The persons into whose mouths the answer is put by the prophet (we may supply before Isa 8:19, "Thus shall ye say to them;" cf., Jer 10:11), are his own children and disciples. The circumstances of the times were very…”
