Isaiah 24:21

In that day; either when God shall punish the apostatical Jews, or about or after that time, or in a time known to God; for this phrase is oft used indefinitely, and without any respect to the time designed in the foregoing passages. The high ones that are on high; the proud and potent enemies of God, and of his people, who possess the high places of the earth. The kings of the earth; either,

1. The great monarchs of the world, who now scorn and trample upon God's people; or,

2. The princes and rulers of Israel or Judah; for the name of king is frequently given in Scripture unto mean and inferior rulers, as Judges 1:7 1 Kings 20:1,12 Psa 119:46, and elsewhere.
