Upon my right hand rise the youth - The right hand is the place of honor, and therefore it was felt to be a greater insult that they should occupy even that place. The word rendered “youth” (פרחח pirchach) occurs nowhere else in the Hebrew Scriptures. It is probably from פרח pârach, “to sprout, germinate, blossom”; and hence, would mean “a progeny,” and would be probably applied to beasts. It is rendered by Jerome, “calamities;” by the Septuagint, “Upon the right hand of the progeny, or brood (βλαστοῦ blastou), they rise,” where Schleusner conjectures that βλαστοι_ blastoi should be read, “On the right hand rise a brood or progeny.” Umbreit renders it, “eine Brut ... a brood.” So Rosenmuller, Noyes, and Schultens. The idea then is, that this rabble rose up, even on his right hand, as a brood of wild animals - a mere rabble that impeded his way.
They push away my feet - Instead of giving place for me, they jostle and crowd me from my path. Once the aged and the honorable rose and stood in my presence, and the youth retired at my coming, but now this worthless rabble crowds along with me, jostles me in my goings, and shows me no manner of respect; compare Job 29:8.
And they raise up against me the ways of their destruction - They raise up against me destructive ways, or ways that tend to destroy me. The figure is taken from an advancing army, that casts up ramparts and other means of attack designed for the destruction of a besieged city. They were, in like manner, constantly making advances against Job, and pressing on him in a manner that was designed to destroy him.
