17 I will wait for the Lord, who is hiding his face from the house of Jacob, and I will hope in him. 18 See, I and the children whom the Lord has given me are signs and portents in Israel from the Lord of hosts, who dwells on Mount Zion. 19 Now if people say to you, "Consult the ghosts and the familiar spirits that chirp and mutter; should not a people consult their gods, the dead on behalf of the living, 20 for teaching and for instruction?" surely, those who speak like this will have no dawn! 21 They will pass through the land, greatly distressed and hungry; when they are hungry, they will be enraged and will curse their king and their gods. They will turn their faces upward, 22 or they will look to the earth, but will see only distress and darkness, the gloom of anguish; and they will be thrust into thick darkness.
Matthew Henry's Commentary on Isaiah 8:17-22
Commentary on Isaiah 8:17-22
(Read Isaiah 8:17-22)
The prophet foresaw that the Lord would hide his face; but he would look for his return in favour to them again. Though not miraculous signs, the children's names were memorials from God, suited to excite attention. The unbelieving Jews were prone to seek counsel in difficulties, from diviners of different descriptions, whose foolish and sinful ceremonies are alluded to. Would we know how we may seek to our God, and come to the knowledge of his mind? To the law and to the testimony; for there you will see what is good, and what the Lord requires. We must speak of the things of God in the words which the Holy Ghost teaches, and be ruled by them. To those that seek to familiar spirits, and regard not God's law and testimony, there shall be horror and misery. Those that go away from God, go out of the way of all good; for fretfulness is a sin that is its own punishment. They shall despair, and see no way of relief, when they curse God. And their fears will represent every thing as frightful. Those that shut their eyes against the light of God's word, will justly be left to darkness. All the miseries that ever were felt or witnessed on earth, are as nothing, compared with what will overwhelm those who leave the words of Christ, to follow delusions.
