Isaiah 30:17

17 A thousand will go in fear before one; even before five you will go in flight: till you are like a pillar by itself on the top of a mountain, and like a flag on a hill.

Isaiah 30:17 Meaning and Commentary

Isaiah 30:17

One thousand [shall flee] at the rebuke of one
A troop of horse, consisting of a thousand men, shall flee upon the attack and onset of a single person, so dispirited should they be, and so possessed of the fear of the enemy; what was promised to them with respect to their enemies is here turned against them, ( Leviticus 26:7 Leviticus 26:8 ) ( Deuteronomy 32:30 ) : at the rebuke of five shall ye flee;
being attacked by a very small number, the whole army should run away: this denotes with what ease they should be routed, and put to flight; and is to be understood, not of what would be at the present time, but of what should come to pass hereafter, when the Chaldean army should come against them; till ye be left as a beacon upon the top of a mountain;
or, "as the mast of a ship", so the Septuagint and other versions. Jarchi says it signifies a high tree, or tall piece of wood fixed in the earth, like a ship's mast F16, set up to give warning of an enemy's approach, and when, and where, sometimes fires used to be kindled; hence the Targum is,

``till ye are left as a burning torch on the top of a mountain.''
The Syriac version renders it, "as a wild ass", solitary and alone: and as an ensign on a hill;
erected as a trophy of victory. The design of the metaphors is to show that there should be few that should escape falling into the enemy's hand, here and there one, that should he scattered about, and be very thin, as beacons and signs are, and should be warnings to others of pursuing the same foolish and sinful methods and practices.
FOOTNOTES:

F16 So Ben Melech says, it is a high piece of wood in a ship, on which they hang an ensign or flag; and so he interprets the ensign in the next clause of a veil, so called, because they lift it up upon the mast.

Isaiah 30:17 In-Context

15 For the Lord, the Holy One of Israel, said, In quiet and rest is your salvation: peace and hope are your strength: but you would not have it so.
16 Saying, No, for we will go in flight on horses; so you will certainly go in flight: and, We will go on the backs of quick-running beasts; so those who go after you will be quick-footed.
17 A thousand will go in fear before one; even before five you will go in flight: till you are like a pillar by itself on the top of a mountain, and like a flag on a hill.
18 For this cause the Lord will be waiting, so that he may be kind to you; and he will be lifted up, so that he may have mercy on you; for the Lord is a God of righteousness: there is a blessing on all whose hope is in him.
19 O people, living in Zion, at Jerusalem, your weeping will be ended; he will certainly have mercy on you at the sound of your cry; when it comes to his ear, he will give you an answer.
