Even so in those days there shall be three or four left by them that search their houses with the sword.
or as in a vineyard that has been harvested a few clusters are left by those who diligently search the vineyard,
That is how it will be in those days. Three or four will be missed by the soldiers who search through the houses to kill everyone.
even so in those days, there will be three or four left by those who search their houses with the sword.
so in those days three or four shall be left by those who search their houses with the sword.
