John Trapp on Psalms 111:9

Verſ. 9. He ſent redemption to his people] Once out of Egypt, ever out of Satans thraldome.

He hath commanded his Covenant for ever] Sic cum popule ſuo pactus eſt ut de ipſius pacti obſervatione certis edict is caverit, as he covenanted, ſo he looketh his commandements ſhould be reſpected, which are as binding to us, as his Covenant is to him; and through grace, his Covenant is as binding to him as thoſe are to us.

Holy and reverend is his Name] Which therefore we ſhould not preſume in a ſudden unmanne[illegible: 1 letter]lineſs to blurt out. The Jews would not pronounce it. The Grecians (as Suidas obſerveth) when they would ſwear by their Jupiter, forbare to mention him This is check to the profaneneſs common amongſt us. Let thoſe that would have their name reverend, labour to be holy as God is holy.
