Jesaja 8:20

In opposition to such a falling away to wretched superstition, the watchword of the prophet and his supporters is this. "To the teaching of God (thorah, Gotteslehre), and to the testimony! If they do not accord with this word, they are a people for whom no morning dawns." The summons, "to the teaching and to the testimony" (namely, to those which Jehovah gave through His prophet, Isa 8:17), takes the form of a watchword in time of battle (Jdg 7:18). With this construction the following אם־לא (which Knobel understands interrogatively, "Should not they speak so, who, etc.?" and Luzzatto as an oath, as in Psa 131:2, "Surely they say such words as have no dawn in them") has, at any rate, all the presumption of a conditional signification. Whoever had not this watchword would be regarded as the enemy of Jehovah, and suffer the fate of such a man. This is, to all appearance, the meaning of the apodosis שׁהר אין־לו אשׁר. Luther has given the meaning correctly, "If they do not say this, they will not have the morning dawn;" or, according to his earlier and equally good rendering, "They shall never overtake the morning light," literally, "They are those to whom no dawn arises." The use of the plural in the hypothetical protasis, and the singular in the apodosis, is an intentional and significant change. All the several individuals who did not adhere to the revelation made by Jehovah through His prophet, formed one corrupt mass, which would remain in hopeless darkness. אשׁר is used in the same sense as in Isa 5:28 and Sa2 2:4, and possibly also as in Sa1 15:20, instead of the more usual כּי, when used in the affirmative sense which springs in both particles out of the confirmative (namque and quoniam): Truly they have no morning dawn to expect. (Note: Strangely enough, Isa 8:19 a…

This chapter, and the four next that follow it (to chap. 13) are all one continued discourse or sermon, the scope of which is to show the great destruction that should now shortly be brought upon the kingdom of Israel, and the great disturbance that should be given to the kingdom of Judah by the king of Assyria, and that both were for their sins; but rich provision is made of comfort for those that feared God in those dark times, referring especially to the days of the Messiah. In this chapter we have, I. A prophecy of the destruction of the confederate kingdoms of Syria and Israel by the king of Assyria (Isa 8:1-4). II. Of the desolations that should be made by that proud victorious prince in the land of Israel and Judah (Isa 8:5-8). III. Great encouragement given to the people of God in the midst of those distractions; they are assured, 1. That the enemies shall not gain their point against them (Isa 8:9, Isa 8:10). 2. That if they kept up the fear of God, and kept down the fear of man, they should find God their refuge (Isa 8:11-14), and while others stumbled, and fell into despair, they should be enabled to wait on God, and should see themselves reserved for better times (Isa 8:15-18). Lastly, He gives a necessary caution to all, at their peril, not to consult with familiar spirits, for they would thereby throw themselves into despair, but to keep close to the word of God (Isa 8:19-22). And these counsels and these comforts will still be of use to us in time of trouble.

8:20 God gave instructions and teachings through the law and through his prophets, such as Isaiah (see 8:16).
