'Add' in the Bible

And king Solomon sweareth by Jehovah, saying, 'Thus doth God to me, and thus He doth add -- surely against his soul hath Adonijah spoken this word;

and now, my father laid on you a heavy yoke, and I add to your yoke; my father chastised you with whips, and I -- I chastise you with scorpions.'

and speaketh unto them, according to the counsel of the lads, saying, 'My father made your yoke heavy, and I add to your yoke; my father chastised you with whips, and I -- I chastise you with scorpions;'

and Jezebel sendeth a messenger unto Elijah, saying, 'Thus doth the gods, and thus do they add, surely about this time to-morrow, I make thy life as the life of one of them.'

And Ben-Hadad sendeth unto him, and saith, 'Thus do the gods to me, and thus do they add, if the dust of Samaria suffice for handfuls for all the people who are at my feet.'
