God again set a certain day, calling it "Today." This he did when a long time later he spoke through David, as in the passage already quoted: "Today, if you hear his voice, do not harden your hearts." (NIV)
Again He sets a definite day, [a new] Today, [and gives another opportunity of securing that rest] saying through David after so long a time in the words already quoted, Today, if you would hear His voice and when you hear it, do not harden your hearts. [Ps. 95:7, 8.] (AMP)
Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts. (KJV)
