New Defender's Study Bible Notes
147:2 build up Jerusalem. Redeemed Israel will offer national praises to Christ, as He fulfills the ancient promises to the nation (Romans 11:26; Zechariah 12:8-10; 13:1; and 14:9).
147:4 number of the stars. Astronomers today estimate there are at least ten trillion stars. To call them all by name, God would have to be omnipresent, naming them simultaneously.
147:5 great power. God is omnipotent as well as omnipresent.
147:5 infinite. Furthermore, He is omniscient!
147:6 down to the ground. In the context, it is possible that this is an implicit reference to the great Flood, as following chronologically the Creation (Psalm 147:4).
147:8 rain for the earth. There was no rain on the earth before the Flood (Genesis 2:5), so a new hydrologic cycle was instituted by God for these post-Flood years. See notes on Psalm 104:10-24.
147:15 commandment. This is not the usual word for “commandment;” rather, it is imrah, usually rendered “word” (see on Psalm 119:11), or a particular word.
147:15 word. Hebrew dabar, commonly meaning the life-giving word of God in general (Psalm 119:9).
147:17 casteth forth his ice. Possibly a reference to the Ice Age following the Flood (perhaps implied in Psalm 147:16). Intense cold such as this would hardly have been known in Israel at any later date.
147:18 sendeth out his word. The same divine word which controls nature (note also Psalm 148:8) speaks to His people (Psalm 147:19).
