(Devarim, Ibid. 6) "And Egypt wrought evil unto us": as it is written (Shemoth 1:10) "Come, let us outsmart it, lest it become numerous, and it be, that if a war break out, etc."
"and they afflicted us": as it is written (Ibid. 11) "And they appointed taskmasters over it in order to afflict it with their toils, and they built treasure cities for Pharaoh."
"and they placed us under hard labor": as it is written (Ibid. 1:13-14) "And Egypt worked the children of Israel with (back-) breaking labor. And they embittered their lives with hard toil: with mortar, and with brick, and with all the labor of the field; all of the labor with which they worked them was (back-) breaking."
