Deuteronomy 33:13
JPS-1917וּלְיוֹסֵ֣ף אָמַ֔ר מְבֹרֶ֥כֶת יְהֹוָ֖ה אַרְצ֑וֹ מִמֶּ֤גֶד שָׁמַ֙יִם֙ מִטָּ֔ל וּמִתְּה֖וֹם רֹבֶ֥צֶת תָּֽחַת׃
And of Joseph he said: Blessed of the LORD be his land; For the precious things of heaven, for the dew, And for the deep that coucheth beneath,
Rashi Commentary
מברכת ה' ארצו BLESSED OF THE LORD BE HIS LAND — It is a fact that there was in the inheritance of all the tribes no land so full of every good thing as Joseph's land (Sifrei Devarim 353:1). ממגד — this means dainties and sweet food. ומתהום [BLESSED OF THE LORD BE HIS LAND] BY THE DEEP — for the deep ascended and moistened it from below (תחת). — You will find that in the case of each tribe Moses' blessing corresponded in some way with Jacob's blessing (cf. for instance this verse with Joseph's blessing in Genesis 49:25).
