אל המנוחה, “to the rest;” the rest which the Lord will provide for them.

ואל הנחלה, “and to the inheritance;” after you have crossed the river Jordan.

כל ימיך על אדמתך, “as long as you live on your land.” According to the plain meaning of the verse, the choice of the word אדמה, “soil, earth,” here instead of ארצך “your land,” may have been dictated by the fact that the Levites did not get any ancestral land, and the other tribes therefore had to see to it that they could have a livelihood, i.e. you who have soil have to look after your brethren who have not been given soil.

כאשר צויתך, “as I have commanded you.” From the formulation, i.e. that G–d had given precise instructions, in this verse, our sages in the Talmud, tractate Chulin folio 28 derive the rule that when slaughtering a mammal both the major part of the gullet and the windpipe of the animal have to be severed. When slaughtering birds, the major part of the windpipe has to be severed. Rabbi Yaakov of Corveillle, found that the numerical value of the letters in the expression כאשר צויתך, equal the numerical value on the words: רוב אחד בעוף ורוב שנים בבהמה, “the major part of one for the bird, and the major part of two for the mammal.” (1047). [What the sages could do without the help of GOOGLE! Ed.] An alternate interpretation of this expression: The three letters in the word אשר, are אלף=1=אחד, for the א, 2 for the ש,=שנים, and the letter ר, short for the word רוב, “major part.”
