Psalms 87 is a tribute to the City God called his own. Jerusalem was built on Mount Moriah and had been a place of importance as far back as Melchizedek, Genesis 14:18-20. In vs. 3 he addresses the City, recounting her glorious history.
Rahab was a woman of Jericho who hid the spies Joshua sent to search out the land before the people crossed the Jordan. She was given sanctuary with them in return for her protection of the spies. Babylon was the capital city of Assyria. Both these references have been used to refer to Egypt even though neither one has a political connection.
He lists other cities from history that are important as reference points to identify Jerusalem. Philistia, Tyre, and Cush are compared to Jerusalem, but they fall short of the glory of Jerusalem. He exalts' the fountains of Jerusalem. Water was always the important item when building a city. Jerusalem had all the important elements.
He praises God's love which stands firm forever and his faithfulness to all generations.
The Heavens praise you, Lord. Who is like you, Lord God Almighty.
You rule over the surging sea. When the waves mount up, you still them. You founded the earth and all that is in it. Your arm is endowed with power. Your hand is strong and your right hand is exalted. I read this as a reference to Jesus as God's right hand.
He sees righteousness and justice as the foundations of God's throne and love and faithfulness going before him.
He pays tribute to David as God's anointed king of Israel. David is a metaphor for Jesus as the Son who will rule over His creation. His enemies will fall before him. God's faithful will be upon him, and through God's name, His power will be exalted. His throne will last as long as heaven endures.
If his sons sin and rebel, I will punish them, but my love will be with them forever.
Praise be to the Lord forever.
Read this Psalm and remember the promises of God to the loved ones of Jesus.
Vs. 17 pleads for the favor of God to rest upon us. The word translated favor may also be translated as beauty. I like that. May the beauty of God rest upon us as we learn to exhibit a heart of wisdom
