||If you are careful to pay heed to my commandments, which I am prescribing to you today, and if you love God your Lord with all your heart and soul, [then God has made this promise]:
Vehayah im-shamoa tishme'u el-mitsvotay asher anochi metsaveh etchem hayom le'ahavah et-Adonay Eloheychem ule'ovdo bechol-levavchem uvechol-nafshechem.
||'I will grant the fall and spring rains in your land at their proper time, so that you will have an ample harvest of grain, oil and wine.
Venatati metar-artsechem be'ito yoreh umalkosh ve'asafta deganecha vetiroshcha veyitsharecha.
This is the second paragraph of the Sh'ma, see Deuteronomy 11:10. This is known as the 'Yoke of the Commandments' (Berakhoth 13a).
|then God has made this promise|
Since the person changes from Moses to God (cf. Midrash HaGadol). See Deuteronomy 29:4.
|fall and spring|
(cf. Targum Yonathan; Taanith 6a). In the Holy Land, the growing season is during the winter, which is the rainy season. Therefore, yoreh is the rain at the beginning of the planting season, and malkosh is at the end.
