Thou art my hiding place; thou shalt preserve me from trouble; thou shalt compass me about with songs of deliverance. Selah.
God Himself is the hiding place: He preserves you from trouble and surrounds you with songs of deliverance.
KJV4For day and night thy hand was heavy upon me: my moisture is turned into the drought of summer. Selah. 5I acknowledged my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the Lord; and thou forgavest the iniquity of my sin. Selah. 6For this shall every one that is godly pray unto thee in a time when thou mayest be found: surely in the floods of great waters they shall not come nigh unto him. 7Thou art my hiding place; thou shalt preserve me from trouble; thou shalt compass me about with songs of deliverance. Selah. 8I will instruct thee and teach thee in the way which thou shalt go: I will guide thee with mine eye. 9Be ye not as the horse, or as the mule, which have no understanding: whose mouth must be held in with bit and bridle, lest they come near unto thee. 10Many sorrows shall be to the wicked: but he that trusteth in the Lord, mercy shall compass him about.
Israel’s prayer book: songs of trust, lament, thanks and praise, many of them by David.
The Lord is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower.
David piles up names for God after being rescued: my rock, my fortress, my deliverer, my high tower.
No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the Lord, and their righteousness is of me, saith the Lord.
Spoken to restored Jerusalem: no weapon formed against God’s servants will finally prosper.
