“. . . when the morning stars sang together, and all the sons of God shouted for joy?” Job 38:7
The phrase “shouted for joy” in this verse is actually a single word (ruwa) in the Hebrew, and it can carry a number of meanings. It is most frequently translated simply “shout,” as when the army of Joshua surrounding Jericho shouted and the walls fell down (Joshua 6:20). In Psalm 100:1, it is translated “make a joyful noise.” It can refer to a shout of alarm or shout of triumph, as well as a shout of joy, but it always refers to a loud shout. In fact, it comes from a root meaning “to split”—a noise that would split eardrums or shatter glass.
In the context of Job 38, the Lord is reminding Job and his friends of the great primeval event of creation. When the earth—which is destined eventually to house God’s throne in the eternal ages to come—was established on solid foundations (on the third day of creation), a resounding noise like mighty thunder—or, better, a gigantic angelic anthem— echoed throughout the universe. An “innumerable company of angels” (Hebrews 12:22), identified in the poetic structure of the Hebrew parallelism in our text as both “morning stars” and “sons of God,” shouted exultantly and sang in unison when the solid earth appeared.
The angels probably were created on the first day of the creation week, immediately after the creation of the universe itself. Even though Satan and other angels later rebelled against God, most of the angels still obey Him, and one day we ourselves will actually hear them singing His praises and shouting for joy when He returns to Earth (1 Thessalonians 4:16; Revelation 4:9-11; 5:11-14; Psalm 148:1-6).
Therefore, “praise ye him all his angels: praise ye him, all his hosts” (Psalm 148:2). Someday, we shall join them in a “joyful noise” at God’s throne. – Dr. Henry M. Morris
