King James Version (KJV)

Hebrews 3:5

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

Verse in context — Hebrews 3

For this [man] was counted worthy of more glory than Moses, inasmuch as he who hath builded the house hath more honour than the house.

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,

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