ma ma vaidarbhy asuyetha
jane tvam mat-parayanam
The Supreme Lord said: O Vaidarbhi, do not be displeased with Me. I know that you are fully devoted to Me. I only spoke in jest, dear lady, because I wanted to hear what you would say.
According to Srila Visvanatha Cakravarti, Lord Krsna spoke the present verse because He thought that lovely Rukmini might be afraid He would again say something to disturb her, or that she might be angry at what He had done.
