II Samuel 22:12 Comentario: Rashi

He put [a protective] darkness around. For [protective] cover as it says, "The pillar of cloud and the darkness separated between Mitzrayim and Yisroel."¹²See Shemos 14:20.

Abundant waters, thick clouds of the sky. From where did the darkness come? They came from thick clouds that sprinkle water on the earth.

Sprinkled. [This is] language that denotes a sieve, [the water] falls to the earth in small droplets. This [same language] is used in many places in Aggadah, "They dice it in a sieve," Some interpret חַשְׁרַת as denoting a binding, that the skies became bound up with clouds because of the water [in them] as [the word] "the spokes"¹³Melochim I, 7:33. used [in connection with] the wheels of a wagon. They are wooden spokes that bond and bind the wheel's perimeter together.
