Exodus 1:13-15

13 And the Egyptians made the sons of Israel serve with harshness.

14 And they made their lives bitter with hard work in mortar and in bricks, and in all [kinds of] work in the field; all their work in which they made them do [was] with harshness.

15 And the king of Egypt spoke to the Hebrew midwives, of which the name of the one [was] Shiphrah, and the name of the other Puah.
