Let’s start with the basics: Israel is divided into blocks (Gush) each with its own number. Each section is divided into parcels (Helka). If the property is an individual home then usually it is registered as Gush Helka, if it’s a flat/apartment or a semi-detached house then each unit usually has its own identifying number as well (Tat Helka – sub parcel).

GUSH - BLOCK, HELKA - PARCEL, leaving MIGRASH to be either PLOT/LOT (which are largely used interchangeably in EN anyway). SHTAR is usually TITLE/DEED, depending on context.
