Isaiah 5:30

And in that day they shall roar against them like the roaring of the sea,.... That is, the Romans against the Jews; whose attacks upon them should be with so much fierceness and power, that it should be like the roaring of the sea, which is very dreadful, and threatens with utter destruction; the roaring of the sea and its waves is mentioned among the signs preceding Jerusalem's destruction by the Romans, Luke 21:25:

and if [one] look unto the land: the land of Judea, when wasted by the Romans, or while those wars continued between them and the Jews; or "into it" k

behold darkness; great affliction and tribulation being signified by darkness and dimness; see Isaiah 8:21

[and] sorrow or "distress", great straits and calamities:

[and], or "even",

the light is darkened in the heavens thereof; in their civil and church state, the kingdom being removed from the one, and the priesthood from the other; and their principal men in both, signified by the darkness of the sun, moon, and stars. Matthew 24:29.
