SEV Biblia, Chapter 12:20
Fueron pues siete hermanos; y el primero tom mujer, y muriendo, no dej simiente;
John Gill's Bible Commentary
Ver. 20. Now there were seven brethren , etc..] In a certain family, at a certain place; perhaps at Jerusalem, who were brethren by the father's side; for such only were reckoned so, and such only did this law oblige: and the first took a wife, and dying left no seed : no child: hence it is clear that the ancient Jews used the word seed, of a single person, as these Sadducees did; though modern ones deny such an use of it in our present controversies with them about the sense of ( Genesis 3:15 22:18); (see Gill on Matthew 22:25).
Matthew Henry Commentary
Verses 18-27 - A right knowledge of the Scripture, as the fountain whence all reveale religion now flows, and the foundation on which it is built, is the best preservative against error. Christ put aside the objection of the Sadducees, who were the scoffing infidels of that day, by setting the doctrine of the future state in a true light. The relation betwee husband and wife, though appointed in the earthly paradise, will not be known in the heavenly one. It is no wonder if we confuse ourselves with foolish errors, when we form our ideas of the world of spirits by the affairs of this world of sense. It is absurd to think that the livin God should be the portion and happiness of a man if he is for eve dead; and therefore it is certain that Abraham's soul exists and acts though now for a time separate from the body. Those that deny the resurrection greatly err, and ought to be told so. Let us seek to pas through this dying world, with a joyful hope of eternal happiness, an of a glorious resurrection.
