12 Praise the LORD, O Jerusalem! Praise your God, O Zion! 13 For he strengthens the bars of your gates; he blesses your sons within you. 15 He sends forth his command to the earth; his word runs swiftly. 16 He gives snow like wool; he scatters hoarfrost like ashes. 19 He declares his word to Jacob, his statutes and ordinances to Israel. 20 He has not dealt thus with any other nation; they do not know his ordinances. Praise the LORD!
