Author: Ethan (or one of his descendants) is the author of this Psalm. Ethan is possibly the Levitical leader and one of the head musicians/singers in the Temple (1 Chronicles 6:42; 15:17-19).
Historical context: God had promised to make David the mightiest King on earth (2 Sam. 7; 1 Kin. 8:23; 1 Chr. 17; 2 Chr. 21:7; Ps. 110). In doing so, God would protect David and David’s descendants (2 Sam. 7:13; 16, 18), and ultimately Messiah Jesus would reign from David’s throne - forever (Luke 1:31-33). Even though Jerusalem was destroyed and no kings were reigning in Jerusalem at this time, God remained faithful and He continues to carry out His promises. God’s promises are - and forever will be - fulfilled through our Lord and Savior Jesus Christ, the Messianic descendant of David (Matt. 1:1; Luke 3:23-28) and the Eternal Prophet, Priest and King of Israel (Heb. 1:1-10:18). Looking beyond the pale of the author’s personal national dilemma - the apparent total ruin of the Davidic monarchy - the author chooses to focus on the LORD and His greatness, regardless of his own personal circumstances and future. As always, man is humbled, and God is glorified. In one word, with restored confidence in God and His Word, the author closes with, “Blessed be the LORD forever! Amen and Amen.” (Psalm 89:52)
The Lord’s Covenant with David and Israel’s Afflictions (89:1-37) Praise and remembrance of God’s love and faithfulness (89:1-4). God’s worthiness to be praise and adored (89:5-14). God’s covenant blessing and protection upon David (89:15-37).
God’s Seeming Neglect of the Davidic Covenant (89:38-52) The Psalmists heartfelt cry (89:46-51). The Psalmists heartfelt distress (89:46-51).
The Doxology - “Blessed be the LORD forever!” (89:52)
