Isaiah 59:19

So shall they fear the name of the Lord from the west, and his glory from the rising of the sun,.... The eastern and western antichrist being destroyed, way shall be made for the spread of the Gospel east and west; which shall be everywhere embraced, and the true worship of God set up; and the glorious name of the Lord, or the Lord who is glorious in his name, nature, perfections, and works, shall be feared and served from the rising of the sun to the setting of the same, or by all nations under the heavens; see Malachi 1:11 and even those that are left in the antichristian states, and escape the general ruin, shall be frightened at his judgments, fear his great and awful name, and give glory to the God of heaven, Revelation 11:13

when the enemy shall come in like a flood; when Satan, the common "enemy" of mankind, the avowed and implacable enemy of Christ and his people, "shall come" into the world, and into the church, as he will in the latter day; and has already entered "like" an impetuous flood, threatening to carry all before him, introducing a flood of immorality and profaneness, as in the days of Noah and Lot, to which the times of the Son of Man's coming are likened, Luke 17:26 or else a flood of error and heresy of all sorts; see Revelation 12:15 and likewise a flood of persecution, as will be at the slaying of the witnesses, that hour of temptation that will come upon all the earth, to try the inhabitants of it, Revelation 3:10. Aben Ezra compares this passage with, and illustrates it by, that time of trouble which will be, such as never was since there was a nation, Daniel 12:1 when this will be the case, which seems to be near at hand:

the Spirit of the Lord shall lift up a standard against him; Christ and his Gospel, or Christ the standard lifted up in the ministry of the Gospel, Isaiah 11:10 a set of ministers shall be raised up, having the everlasting Gospel, which they shall publish to all nations, and which shall have an universal spread; and by means of which the earth shall be filled with the knowledge of the Lord as the waters cover the sea; and which will be a sufficient check to the enemy's flood of immorality, error, and persecution; and which, after this, shall be no more; see Revelation 14:6. Some render the words, "when he", the glorious name of the Lord, or he who is the glory of the Lord, the brightness of his glory;

shall come like a narrow flood, that flows with great swiftness and force, and carries all before it;

the Spirit of the Lord lifting him up for a standard l, that is, in the ministry of the word; "so shall they fear", c. then multitudes shall serve the Lord, and worship him. The Targum is,

"they that afflict shall be as the overflowing of the river Euphrates; by the word of the Lord shall they be broken;''

and Vitringa thinks there is an allusion to the river Euphrates; interpreting the enemy of the Ottoman Turks, Tartars, and Scythians, stirred up by Satan to distress the church: all this may be applied to the case of particular believers under the assaults of Satan their grand enemy; who seeks all occasions to disturb their peace and destroy their comfort, though he cannot ruin their souls; he comes in, not only into their houses where they dwell, and gives them disturbance there; and into the house of God where they worship, and does all he can to hinder them in attending on the word and ordinances, and to prevent all usefulness, edification, and comfort thereby; but he enters into their hearts, and stirs up the corruptions of their nature, and causes these to rise like a flood, which threaten with bringing them into captivity to the law of sin and death; and attacks them with violent temptations, suggesting that they are not the people of God, the redeemed of the Lamb, or regenerated by the Spirit, but are hypocrites, and never had the work of grace on their hearts; aggravating their sins, and telling them they have sinned the sin against the Holy Ghost, and there is no pardon for them; and at other times filling their minds with blasphemous and atheistical thoughts; all which come upon them sometimes with so much force, that it is like an overflowing flood that threatens with utter destruction; when the Spirit of the Lord within them, who is greater than he that is in the world, lifts up Christ as an ensign or standard to them; and directs them to his blood for peace and pardon, for the cleansing of their souls and the atonement of their sins; where they may see and read, in legible characters, the free and full remission of their sins, and an entire satisfaction to the justice of God for them; and he holds up and holds out the righteousness of Christ unto them, with which God is well pleased, his justice satisfied, and his law made honourable; and by which they are justified from all things, and secured from all charges and condemnation; and who also leads them to the person, power, and grace of Christ, to preserve them in grace to glory, to keep them from falling, and present them faultless before the throne of God; the consequence of which is a check to Satan's temptations; an antidote to the doubts and fears he injects; and an abundance of spiritual peace and comfort; as well as it engages to fear the Lord and his goodness.
