'Today' in the Bible

For to which of the angels did He ever say, You are My Son; today I have become Your Father, or again, I will be His Father, and He will be My Son?

Wherefore (as the Holy Ghost saith, To day if ye will hear his voice,

But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.

While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation.

Therefore, while the promise of entering His rest still remains and is freely offered today, let us fear, in case any one of you may seem to come short of reaching it or think he has come too late.

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.

So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee.

This illustration for today indicates that the gifts and sacrifices being offered could not clear the conscience of a worshiper,

Jesus Christ the same yesterday, and to day, and for ever.
