King James Version (KJV)

Hebrews 3:6

“But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.”

Verse in context — Hebrews 3

For every house is builded by some [man]; but he that built all things [is] God.

And Moses verily [was] faithful in all his house, as a servant, for a testimony of those things which were to be spoken after;

But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.

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

Harden not your hearts, as in the provocation, in the day of temptation in the wilderness:

Jesus as the ultimate High Priest and fulfillment of the Old Covenant.
