The sons of Jacob answered Shechem and Hamor his father with deceit

The abstract noun "deceit" can be stated as the verb "lied." Alternate translation: "But the sons of Jacob lied to Shechem and Hamor when they answered them" (See: rc://en/ta/man/jit/figs-abstractnouns)

Shechem had defiled Dinah

This means that Shechem had greatly dishonored and disgraced Dinah by forcing her to sleep with him. See how you translated "defiled" in Genesis 34:5.
