'Add' in the Bible

and whereas my father laid a heavy yoke upon you, I will add to your yoke: my father chastised you with whips, but I will chastise you with scorpions.

and spoke to them according to the advice of the young men, saying, My father made your yoke heavy, but I will add to it; my father chastised you with whips, but I will chastise you with scorpions.
