Ps 15:2
15:2 He that {a} walketh uprightly, and worketh righteousness,
     and speaketh the truth in his heart.

     (a) He shows that we cannot call on God unless we trust in
         him.

Ps 15:4
15:4 {b} In whose eyes a vile person is contemned; but he
     honoureth them that fear the LORD. [He that] sweareth to
     [his own] hurt, and changeth not.

     (b) He who flatters not the ungodly in their wickedness.

Ps 15:5
15:5 [He that] {c} putteth not out his money to usury, nor
     taketh reward against the innocent. He that doeth these
     [things] {d} shall never be moved.

     (c) To the hinderance of his neighbour.
     (d) That is, will not be cast from the Church as a
         hypocrite.
