כִּכְלוּב֙ מָ֣לֵא ע֔וֹף כֵּ֥ן בָּתֵּיהֶ֖ם מְלֵאִ֣ים מִרְמָ֑ה עַל־כֵּ֥ן גָּדְל֖וּ וַֽיַּעֲשִֽׁירוּ׃
As a cage is full of birds, So are their houses full of deceit; Therefore they are become great, and waxen rich;
Ben Sira
[Those who accustom themselves to licentiousness] are like a spark that ignites a coal. As a cage is full of birds, so are their houses full of deceit [Jeremiah 5:27].
