'Add' in the Bible

And answered them after the advice of the young men, saying, My father made your yoke heavy, but I will add thereto: my father chastised you with whips, but I will chastise you with scorpions.

And said unto them, Ye shall not bring in the captives hither: for whereas we have offended against the LORD already, ye intend to add more to our sins and to our trespass: for our trespass is great, and there is fierce wrath against Israel.
