Gálatas 3

Pero las promesas fueron hechas a Abraham y a su descendencia. No dice: Y a sus descendencias, como de muchas, sino como de una: Y a su descendencia, la cual es Cristo.

A Abraham fueron hechas las promesas, y á su simiente. No dice: Y á las simientes, como de muchos; sino como de uno: Y á tu simiente, la cual es Cristo.

Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.

Now the promises were spoken to Abraham and to his offspring. He doesn’t say, “To descendants”, as of many, but as of one, “To your offspring”, which is Christ.
