The voice of thy thunder [was] in the heaven: the lightnings lightened the world: the earth trembled and shook.
Ver. 18. The voice of thy thunder was in the heaven] Heb. in the sphere or round orb of the air. Of the thunder in the air, see Job 37:2-5 Psa 29:1-11 This made the Egyptians say, Let us flee, for God fighteth for Israel against us.
The lightnings lightened the world] Such flakes of fire there were with flashes of lightning, as darkened the sun, and made the whole heaven seem to be on a light fire.
