Selah

“He sends from heaven and saves me, rebuking those who hotly pursue me; Selah – God sends His love and His faithfulness.” Psalm 57:3
Hebrew poetry and song is not so much linked through rhyme and metre (rhythm) as western music is; rather, it is based on the connections and contrasts between thoughts or ideas. The word Selah appears many times in the Psalms. It indicates a break in the passage, time to meditate on what has been said, and also as a linkage to the next passage, thought, or idea.
The thought contained in the first passage is one of God’s deliverance from our enemies. The linkage to the second thought is through the word ‘sends’. In the first passage, David is being pursued by his enemies and calls to God to ‘send’ from heaven and save him. We would think that the answer to this prayer would be for God to send an angel to fight off the enemies, or to confuse them so that David could escape. But the Selah connects to the second thought: ‘God sends His love and His faithfulness’. God didn’t send an angel to deliver David physically, but He did send His love and faithfulness, letting David know in his heart that God would keep all the promises He had made to him.
If you think about it, the spiritual answer to prayer is more important and more valuable than the physical answer to prayer. Many times we ask for physical healing, which may leave us short-changed if God’s plan is to build us up to be spiritually strong. We may pray for our physical needs to be met, but if God were to answer these prayers and not meet our spiritual needs, we would only have temporary relief.
