Exodus 1:17 ASV

¹⁵  And the king of Egypt spake to the Hebrew midwives, of whom the name of the one was Shiphrah, and the name of the other Puah:

¹⁶  and he said, When ye do the office of a midwife to the Hebrew women, and see them upon the birth-stool; if it be a son, then ye shall kill him; but if it be a daughter, then she shall live.

¹⁷  But the midwives feared God, and did not as the king of Egypt commanded them, but saved the men-children alive.

¹⁸  And the king of Egypt called for the midwives, and said unto them, Why have ye done this thing, and have saved the men-children alive?

¹⁹  And the midwives said unto Pharaoh, Because the Hebrew women are not as the Egyptian women; for they are lively, and are delivered ere the midwife come unto them.
