Hebrews 3:12-14

Young's Literal Translation

¹² See, brethren, lest there shall be in any of you an evil heart of unbelief in the falling away from the living God,

¹³ but exhort ye one another every day, while the To-day is called, that none of you may be hardened by the deceitfulness of the sin,

¹⁴ for partakers we have become of the Christ, if the beginning of the confidence unto the end we may hold fast,
