King James Version (KJV)

Hebrews 10:19

“Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,”

Verse in context — Hebrews 10

And their sins and iniquities will I remember no more.

Now where remission of these [is, there is] no more offering for sin.

Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus,

By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;

And [having] an high priest over the house of God;

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