“ One who goes, he and his wife, overseas, and he comes [back] [with] his wife and his sons, and says, "The wife that went with me overseas, this is she, and these are her sons" — he does not need to bring a proof, neither for the wife or for the sons. "... she died, and these are her sons" — he brings a proof for the sons, but does not bring a proof for the wife. [One who comes back from overseas and says,] "I married a wife overseas, this is she and these are her sons" — he brings a proof for the wife, but does not bring a proof for the sons. ”
