New Defender's Study Bible Notes
100:3 not we ourselves. The sense of this command is: “Learn without question that Jehovah is the Creator God.” Contrary to evolutionary theory, which views man as the pinnacle of the evolutionary process and as having perfected his own evolution once he evolved bi-pedality, it was God alone who made us, not we ourselves!
100:3 sheep of His pasture. The Lord is our Good Shepherd (John 10:11). Note also Psalm 95:7, as well as Psalm 23:1, Isaiah 40:11; etc.
