Mark 12:23 Meaning

21And the second took her, and died, neither left he any seed: and the third likewise.

22And the seven had her, and left no seed: last of all the woman died also.

23In the resurrection therefore, when they shall rise, whose wife shall she be of them? for the seven had her to wife.

24And Jesus answering said unto them, Do ye not therefore err, because ye know not the scriptures, neither the power of God?

25For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven.
