Revised Standard edition sez it as, "22: "When men strive together, and hurt a woman with child, so that there is a miscarriage, and yet no harm follows, the one who hurt her shall be fined, according as the woman's husband shall lay upon him; and he shall pay as the judges determine."

Suppose somebody who's both anti-abortion, and all about the KJV, might see that as proof that you have to stick with the KJV- it can be interpreted to fit pre-existing politics!
