Mark 12:25 (KJV)

Now there were seven brethren: and the first took a wife, and dying left no seed.

And the second took her, and died, neither left he any seed: and the third likewise.

And the seven had her, and left no seed: last of all the woman died also.

In the resurrection therefore, when they shall rise, whose wife shall she be of them? for the seven had her to wife.

And Jesus answering said unto them, Do ye not therefore err, because ye know not the scriptures, neither the power of God?

And as touching the dead, that they rise: have ye not read in the book of Moses, how in the bush God spake unto him, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob?

He is not the God of the dead, but the God of the living: ye therefore do greatly err.

And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all?

And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord:

And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
