[10] Wherefore I was grieved generation, and said, alway err in their heart; and they not known ways. [11] So I sware in wrath, not enter into rest.) [12] Take heed, brethren, in any an evil heart of unbelief, in departing from the living God. [13] But exhort one another daily, while it is called To day; any of be hardened through the deceitfulness of sin. [14] For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end; [15] While it is said, To day if ye will hear his voice, harden not hearts, as in the provocation.
