Hebreos 4

again he ordains a certain day, today, speaking by David after so long a time, just as had been said before, “Today, if you hear his voice, do not harden your hearts.”

Determina otra vez un cierto día, diciendo por David: Hoy, después de tanto tiempo; como está dicho: Si oyereis su voz hoy, no endurezcáis vuestros corazones.

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.”
