Numbers 20:15

How our fathers went down into Egypt
Jacob and his twelve sons, with their children:

and we have dwelt in Egypt a long time;
even the space of four hundred and thirty years, ( Exodus 12:40 Exodus 12:41 )

and the Egyptians vexed us and our fathers;
used them ill, brought them into bondage, and made their lives bitter, laid heavy tasks and burdens upon them, as well as slew their male children, see ( Exodus 1:7-22 ) .
