KJV:
Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;
NKJV:
having abolished in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man from the two, thus making peace,
NIV:
by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace,
Interpretation:
Christ abolished the enmity between Jews and Gentiles by removing the law's dividing wall. He set aside the law of commandments in His flesh. His purpose was to create one new humanity from two groups. The verse shows that Christ removes barriers between people. The law that separated Jews and Gentiles is abolished in Christ. Christ creates unity where there was division. The new humanity in Christ replaces the old divisions. The verse teaches that Christ brings people together through His work on the cross.
