JFB : Psalms 15

      @Ps 15:1-5. Those who are fit for communion with God may be known by a conformity to His law, which is illustrated in various important particulars.

      1. abide--or, "sojourn" (compare @Ps 5:4), where it means under God's protection here, as (@Ps 23:6,27:4,6) communion.
      tabernacle--seat of the ark (@2Sa 6:17), the symbol of God's presence.
      holy hill--(Compare @Ps 2:6).

      2. walketh--(Compare @Ps 1:1).
      uprightly--in a complete manner, as to all parts of conduct (@Ge 17:1), not as to degree.
      worketh--or, "does."
      righteousness--what is right.
      in his heart--sincerely (@Pr 23:7).

      3. He neither slanders nor spreads slander.

      4. Love and hate are regulated by a regard to God.
      sweareth . . . hurt--or what so results (compare @Le 5:4).

      5. (Compare @Le 25:37 De 23:19,20).
      usury is derived from a verb meaning "to bite." All gains made by the wrongful loss of others are forbidden.
      taketh reward, &c.--The innocent would not otherwise be condemned (compare @Ex 23:8 De 16:19). Bribery of all sorts is denounced.
      doeth these, &c.--Such persons admitted to God's presence and favor shall never be moved (@Ps 10:6 13:5).
