(Ibid. 21) "And the L–rd went before them by day with a pillar of cloud": We find there to have been seven clouds: here, (Numbers 14:14) twice, (Ibid. 9:19), (Exodus 40:36), (Ibid. 37), (Ibid. 38)—Seven clouds: four on four sides, one above, one below, and one going before them, lifting what was low, and lowering what was high, as it is written (Isaiah 40:4) "Let every valley be raised, and every mountain and hill be lowered. Let the rugged ground become level and the ridges become a plain." And it would kill the snakes and scorpions before them and sweep and sprinkle before them.
