Hebreos 4

After a long time, again naming a certain day, he says in David, Today (as he had said before), Today if you will let his voice come to your ears, be not hard of heart,

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.”
