5 For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son?
7 Wherefore (as the Holy Ghost saith , To day if ye will hear his voice,
13 But exhort one another daily , while it is called To day; lest any of you be hardened through the deceitfulness of sin.
15 While it is said , To day if ye will hear his voice, harden not your hearts, as in the provocation.
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.
5 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.
8 Jesus Christ the same yesterday, and to day, and for ever.
