12 Extol the Lord, Jerusalem; praise your God, Zion. 13 He strengthens the bars of your gates and blesses your people within you. 14 He grants peace to your borders and satisfies you with the finest of wheat. 15 He sends his command to the earth; his word runs swiftly. 16 He spreads the snow like wool and scatters the frost like ashes. 17 He hurls down his hail like pebbles. Who can withstand his icy blast? 18 He sends his word and melts them; he stirs up his breezes, and the waters flow. 19 He has revealed his word to Jacob, his laws and decrees to Israel. 20 He has done this for no other nation; they do not know his laws.[1]Praise the Lord.

Commentary on Psalm 147:12-20

(Read Psalm 147:12-20)

The church, like Jerusalem of old, built up and preserved by the wisdom, power, and goodness of God, is exhorted to praise him for all the benefits and blessings vouchsafed to her; and these are represented by his favours in the course of nature. The thawing word may represent the gospel of Christ, and the thawing wind the Spirit of Christ; for the Spirit is compared to the wind, John 3:8. Converting grace softens the heart that was hard frozen, and melts it into tears of repentance, and makes good reflections to flow, which before were chilled and stopped up. The change which the thaw makes is very evident, yet how it is done no one can say. Such is the change wrought in the conversion of a soul, when God's word and Spirit are sent to melt it and restore it to itself.
