Keluaran 19:18

19:18 Now Mount Sinai was completely covered with smoke because the Lord had descended on it in fire, and its smoke went up like the smoke of a great furnace, ¹  and the whole mountain shook ²  violently.

Ayub 9:6

9:6 he who shakes the earth out of its place ³ 

so that its pillars tremble; ⁴ 

[19:18]  ¹ sn The image is that of a large kiln, as in Gen 19:28.

[19:18]  ² tn This is the same word translated “trembled” above (v. 16).

[9:6]  ³ 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]  ⁴ 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).
