Ayub 9:6

9:6 he who shakes the earth out of its place ¹ 

so that its pillars tremble; ² 

Ayub 26:11

26:11 The pillars ³  of the heavens tremble

and are amazed at his rebuke. ⁴ 

[9:6]  ¹ 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.

[9:6]  ² tn The verb הִתְפַלָּצ (hitfallats) 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; and Ps 55:6).

[26:11]  ³ sn H. H. Rowley (Job [NCBC], 173) says these are the great mountains, perceived to hold up the sky.

[26:11]  ⁴ sn The idea here is that when the earth quakes, or when there is thunder in the heavens, these all represent God’s rebuke, for they create terror.
