New Defender's Study Bible Notes
89:5 the heavens. Psalm 89:5-8 of this unique psalm indicates that its setting is in heaven, with “the congregation of saints” assembled around God’s throne, eulogizing the Lord and His mighty works. These “saints” are the holy angels, “the sons of the mighty” (Psalm 89:6), gathered in “the assembly of the saints” (Psalm 89:7) to give praise to God.
89:10 Rahab. This is not a reference to the Jericho woman of Joshua’s time, but to Satan, the old “dragon” (see Isaiah 51:9). The two names are slightly different in Hebrew spelling, although pronounced and transliterated the same in English. The word used here means “proud” and is so translated in Job 9:13 and 26:12. In fact, the name of “Pride” can appropriately be assigned to Satan, for he is the very father of pride, presuming to war against his Creator! In a great day to come, he will indeed be “broken in pieces” and consigned forever to the lake of fire.
89:11 earth also is thine. God is surely worthy of praise and worship. He has created heaven and earth, and therefore they belong to Him.
89:12 created them. North-south directions could only be meaningful on a spherical planet if there are north and south “poles” on it—either geographic poles (formed by the establishment of an axial rotation) or magnetic poles (formed by the initiating of rotating electrical currents deep in the earth’s core), or both. These were evidently created by God on the first day of Creation Week when God established the cycle of day and night (Genesis 1:3-4).
89:20 anointed. David was “anointed” as king, but he is also a type of the Messiah (i.e., the “anointed one”), as is evident from Psalm 89:27-29,36-37. At this point, Psalm 89 becomes essentially a Messianic psalm, fulfilled in part in the experiences of David but ultimately fulfilled only in Christ.
89:25 in the rivers. This indicates that the “anointed” one (Psalm 89:20) is owner of all the life-sustaining waters of the world.
89:27 my firstborn. As God’s “firstborn,” He is the heir of God’s created world (Psalm 2:8). All the kings of the earth are stewards, not owners.
89:37 for ever as the moon. The moon will exist forever, as will the throne of Christ.
89:38 wroth with thine anointed. How could God be angry with His “anointed”—that is, His Messiah? He had just promised that His seed and His throne would—like the sun—endure forever (Psalm 89:36). The only rationale for such an anomaly would be that He had been “covered...with shame” (Psalm 89:45), that is, God “hath made Him to be sin for us, who knew no sin” (II Corinthians 5:21). In his persecution by Saul and other enemies, even after being anointed as future king, David was a type of the Messiah, but the ultimate fulfillment awaited the crucifixion of Christ.
89:52 Amen, and Amen. This verse constitutes the doxology that ends Book III of the Book of Psalms.
