Job 9:6 New English Translation

⁶he who shakes the earth out of its place^[a]
so that its pillars tremble,^[b]

Job 9:6 sn Shakes the earth out of its place probably refers to earthquakes, although some commentators protest against this in view of the idea of the pillars. In the ancient world the poetical view of the earth is that it was a structure on pillars, with water around it and under it. In an earthquake the pillars were shaken, and the earth moved.
Job 9:6 tn The verb הִתְפַּלָּץ (hitpallats) is found only here, but the root seems clearly to mean “to be tossed; to be thrown about,” and so in the Hitpael “quiver; shake; tremble.” One of the three nouns from this root is פַּלָּצוּת (pallatsut), the “shudder” that comes with terror (see Job 21:6; Isa 21:4; Ezek 7:18; Ps 55:6).
