'Add' in the Bible

And now whereas my father did lade you with a heavy yoke, I will add to your yoke: my father chastised you with whips, but I will chastise you with scorpions.

and spake to them after the counsel 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 ye purpose that which will bring upon us a trespass against Jehovah, to add unto our sins and to our trespass; for our trespass is great, and there is fierce wrath against Israel.
