Exodus 4:25

Sharp stone -Not “knife,” as in the margin. Zipporah used a piece of flint, in accordance with the usage of the patriarchs. The Egyptians never used bronze or steel in the preparation of mummies because stone was regarded as a purer and more sacred material than metal. Cast it at his feet -Showing at once her abhorrence of the rite, and her feeling that by it she had saved her husband’s life. A bloody husband -Literally, “a husband of blood,” or “bloods.” The meaning is: The marriage bond between us is now sealed by blood.
