Hebrews 10:5

5 Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:

Ver. 5. But a body hast thou prepared ] A metaphor from mechanics, who do artificially fit one part of their work to another, and so finish the whole, κατηρτισω . God fitted his Son’s body to be joined with the Deity, and to be an expiatory sacrifice for sin.
