10 “They have called the people blessed who have these things”. O men that speak vanity! They have lost the true right hand, wicked and perverse, they have put on the benefits of God inversely. O wicked ones, O speakers of vanity, O strange children! What was on the left hand, they have set on the right. What do you, David? What do you, Body of Christ? What do ye, members of Christ? What do ye, not strange children, but children of God?...What do you say? Say ye with us, “Blessed is the people whose Lord is their God.”
