Exodus 4
24 Ref And it cometh to pass in the way, in a lodging place, that Jehovah meeteth him, and seeketh to put him to death;
25 Ref and Zipporah taketh a flint, and cutteth off the foreskin of her son, and causeth `it' to touch his feet, and saith, `Surely a bridegroom of blood `art' thou to me;'
26 and He desisteth from him: then she said, `A bridegroom of blood,' in reference to the circumcision.
