Verse 8
I have set the Lord always before me - This verse, and all to the end of Psa 16:11, are applied by St. Peter to the death and resurreetion of Christ. Act 2:25, etc.
In all that our Lord did, said, or suffered, he kept the glory of the Father and the accomplishment of his purpose constantly in view. He tells us that he did not come down from heaven to do his own will, but the will of the Father who had sent him. See Joh 17:4.
He is at my right hand - That is, I have his constant presence, approbation, and support. All this is spoken by Christ as man.
I shall not be moved - Nothing can swerve me from my purpose; nothing can prevent me from fulfilling the Divine counsel, in reference to the salvation of men.
