Isaiah 14:30
And the firstborn of the poor shall feed, and the needy shall lie down in safety: and I will kill thy root with famine, and he shall slay thy remnant.
And the firstborn of the poor shall feed,.... That is, the Jews, who were brought very low in the times of Ahaz, reduced to the greatest straits and difficulties; for so the word "firstborn" may signify the chief, or those who were of all the poorest, and in the greatest distress; these, in the times of Hezekiah, shall enjoy abundance of good things, and under his gentle government shall feed like a flock of sheep in good pastures; this signifying, that though he should be like a serpent, harmful to his enemies, yet should be kind and tender unto, and take great care of his own subjects, and under whom they should have great plenty and prosperity:
and the needy shall lie down in safety; like a flock of sheep, secure from beasts of prey, under the care of a faithful and vigilant shepherd; this shows that the Jews should not only have plenty of good things, but should live in the greatest security, without fear of any enemy, or danger from them:
and I will kill thy root with famine; this is said to Palestine, compared to a tree, whose root is dried up for want of moisture, and so dies; and the meaning is, that a sore famine should rage in their country, and utterly destroy them:
and he shall slay thy remnant: that is, Hezekiah should slay with the sword those that were left of the famine.
