God again designated a certain day as “Today,” when a long time later He spoke through David as was just stated: “Today, if you hear His voice, do not harden your hearts.”
KJV
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.
ASV
he again defineth a certain day, To-day, saying in David so long a time afterward (even as hath been said before), To-day if ye shall hear his voice, Harden not your hearts.
