Exodus 1:16

and he said, When ye do the office of a midwife to the Hebrew women, and see them upon the stools, in determining the sex; if it be a son, then ye shall kill him, the male children should be killed right after birth; but if it be a daughter, then she shall live. Whether these two women were the only midwives in Israel, or whether they were the heads of the order of midwives, is immaterial, the devilish command to use inhuman violence referred to all male children among the Hebrews.
