16 He spreads snow like a blanketand scatters frost like dust.
17 He sends hail like gravel;no one can endure the cold he sends!
18 Then he gives a command, and the ice melts;he sends the wind, and the water flows.
19 He gives his message to his people,his instructions and laws to Israel.
20 He has not done this for other nations;they do not know his laws.Praise the Lord!
