Men are commanded by God not to marry for a second time nor are they supposed to ever marry a divorced woman. If this happens, it is unlikely that the family will ever be reunited. This situation is very damaging to the first family.
Jesus said in Luke 16:18, “Whosoever putteth away his wife, and marrieth another, committeth adultery; and whosoever marrieth her that is put away from her husband committeth adultery.”
