7 therefore the Lord is about to bring against them the mighty floodwaters of the Euphrates- the king of Assyria with all his pomp. It will overflow all its channels, run over all its banks
23 They are armed with bow and spear; they are cruel and show no mercy. They sound like the roaring sea as they ride on their horses; they come like men in battle formation to attack you, Daughter Zion."
(Read Jeremiah 6:18-30)
God rejects their outward services, as worthless to atone for their sins. Sacrifice and incense were to direct them to a Mediator; but when offered to purchase a license to go on in sin, they provoke God. The sins of God's professing people make them an easy prey to their enemies. They dare not show themselves. Saints may rejoice in hope of God's mercies, though they see them only in the promise: sinners must mourn for fear of God's judgments, though they see them only in the threatenings. They are the worst of revolters, and are all corrupters. Sinners soon become tempters. They are compared to ore supposed to have good metal in it, but which proves all dross. Nothing will prevail to part between them and their sins. Reprobate silver shall they be called, useless and worthless. When warnings, corrections, rebukes, and all means of grace, leave men unrenewed, they will be left, as rejected of God, to everlasting misery. Let us pray, then, that we may be refined by the Lord, as silver is refined.
Matthew Henry's Commentary on Isaiah 8:7
Commentary on Isaiah 8:1-8
(Read Isaiah 8:1-8)
The prophet is to write on a large roll, or on a metal tablet, words which meant, "Make speed to spoil, hasten to the prey:" pointing out that the Assyrian army should come with speed, and make great spoil. Very soon the riches of Damascus and of Samaria, cities then secure and formidable, shall be taken away by the king of Assyria. The prophet pleads with the promised Messiah, who should appear in that land in the fulness of time, and, therefore, as God, would preserve it in the mean time. As a gentle brook is an apt emblem of a mild government, so an overflowing torrent represents a conqueror and tyrant. The invader's success was also described by a bird of prey, stretching its wings over the whole land. Those who reject Christ, will find that what they call liberty is the basest slavery. But no enemy shall pluck the believer out of Emmanuel's hand, or deprive him of his heavenly inheritance.
