Jesus had already given a parable about leaven in a lump of dough to illustrate the spread of the Kingdom (Matthew 13:33). It was to come through silent, steady growth just as leaven spreads through bread dough.
Nagbigay na si Jesus ng talinhaga tungkol sa lebadura na kahalo ng masa ng harina, upang ipakita ang pagkalat ng Kaharian (Mateo 13: 33). Ito ay darating nang tahimik at patuloy tulad ng pagkalat ng pampaalsa sa masa ng tinapay.
