Galatians 3:29

And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.

And heirs. So G. But A B C Delta 'Aleph (') f, Vulgate, omit "and." Christ is "Abraham's seed:" ye are "one in Christ" (Galatians 3:28), and one with Christ, as having "put on Christ" (Galatians 3:27); therefore YE [ humeis (G5210): emphatic] are "Abraham's seed," - tantamount to saying (whence the "and" is omitted), ye are "heirs according to (in the way of) the promise" (not 'by the law,' Galatians 3:18); for it was to Abraham's seed that the inheritance was promised (Galatians 3:16). Thus he arrives at the truth which he set out with (Galatians 3:7). But one "seed" of a righteous succession. One faultless grain of human nature was found by God Himself, the source of a new imperishable seed: "the seed" (Psalms 22:30) who receive from Him a new nature and name (Genesis 3:15; Isaiah 53:10; John 12:24). In Him David's line becomes extinct. He died without posterity. But He lives and shall reign on David's throne. No one has a legal claim to it but Himself, He being the only direct representative (Ezekiel 21:27). His spiritual seed derive birth from the travail of His soul, being born again of His Word, the incorruptible seed (John 1:12; Romans 9:8; 1 Peter 1:23).
