כָּל־הַנִּמְצָ֖א יִדָּקֵ֑ר וְכָל־הַנִּסְפֶּ֖ה יִפּ֥וֹל בֶּחָֽרֶב׃
만나는 자는 창에 찔리겠고 잡히는 자는 칼에 엎드러지겠고
Rashi on Isaiah
and anyone who takes refuge with the people of the city to be included with them in the siege, shall fall by the sword when the city capitulates. נִסְפֶּה is an expression similar to (Deut. 29:18): “To add the unintentional sins to the lustful ones (סְפוֹת)”; (infra 29:1) “Add year upon year (סְפוּ)”; (Jer. 7:21) “Add (סְפוּ) to your sacrifices.” [akojjlir in O.F.], to join.
