[Col 3:10, 12 KJV]
10 And have put on the new [man], which is renewed in knowledge after the image of him that created him: ...
12 Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering;
[Col 3:11 KJV] 11 Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond [nor] free: but Christ [is] all, and in all.
[Gal 3:28 KJV] 28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
[Gal 3:29 KJV] 29 And if ye [be] Christ's, then are ye Abraham's seed, and heirs according to the promise.
