Hebrews 4:7

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.

he again defines a certain day, today, saying through David so long a time afterward (just as has been said), "Today if you will hear his voice, Don't harden your hearts."

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.

again He doth limit a certain day, `To-day,' (in David saying, after so long a time,) as it hath been said, `To-day, if His voice ye may hear, ye may not harden your hearts,'

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.”
