He sendeth forth his commandment upon earth - That is, with reference to the productions of the earth; to the changes which occur; to the seasons; to snow, frost, ice, cold, heat, wind; and he is universally and immediately obeyed. Nature everywhere yields a ready acquiescence to his will.

His word runneth very swiftly - As if it hastened to obey him. There is no delay. Compare the notes at Psalm 33:9 : "He spake, and it was done; he commanded, and it stood fast." Snow, and frost, and ice, and cold, and heat, and wind, are entirely obedient to him. There is no reluctance in obeying him; there is no delay.

He sendeth forth has commandment - His substantial word. It is here personified, מימרא meymra, Chaldee; and appears to be a very active agent running every where, and performing the purposes of his will.

He sendeth forth his commandment upon earth,.... Which Kimchi interprets of rain, which causes the wheat to grow; since afterwards mention is made of snow, and of hoar frost and ice. Aben Ezra understands it of the decree of God, which he executes on earth. The Targum, of the "Memra", or Word of the Lord; the essential Word, the Messiah; whom the Lord sent on earth to perform the great work of redemption and salvation; and who came speedily, and tarried not when the fulness of time was come, as follows. It may design God's word of providence, which answers to his word of power in the first creation of all things; and which orders everything done in the earth, and is instantly obeyed; which agrees with Psalm 147:18. Or rather the word of the Gospel; the doctrines and ordinances of divine revelation, agreeably to Psalm 147:19; and so may have respect to the mission of the apostles of Christ, and ministers of the word, to go into all the earth, and preach the Gospel to every creature;

his word runneth very swiftly; so the Gospel did in the first times of it, like lightning, from one end of the heaven to the other; the words of it went into all the world, and the sound of it unto the ends of the earth; it had a free course, and was glorified: and so it will in the latter day, when many shall run to and fro, and knowledge shall be increased; see Romans 10:18.

He sendeth forth his {k} commandment upon earth: his word runneth very {l} swiftly.

(k) His secret working in all creatures is as a command to keep them in order and to give them moving and force.

(l) For immediately and without resisting all things obey him.

147:15 Commandment - Which is sufficient without any instruments to execute whatsoever pleaseth him. Swiftly - The thing is done without delay.

15-18. God's Word, as a swift messenger, executes His purpose, for with Him to command is to perform (Ge 1:3; Ps 33:9), and He brings about the wonders of providence as easily as men cast crumbs.

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, Joh 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.
