The land which you are about to occupy is not like Egypt, the place you left, where you could plant your seed and irrigate it by yourself, just like a vegetable garden.
Ki ha'arets asher atah va-shamah lerishtah lo che'erets Mitsrayim hi asher yetsatem misham asher tizra et-zar'acha vehishkita veraglecha kegan hayarak.
||But the land which you are crossing to occupy is a land of mountains and valleys, which can be irrigated only by the rain.
Veha'arets asher atem overim shamah lerishtah erets harim uveka'ot limtar hashamayim tishteh-mayim.
(Targum Yonathan). Or, 'with your feet' (Rashi; Septuagint).
