“This will be the land that will fall to you [lakhem] as an inheritance” – what is “lakhem”? It is fitting for you [lakhem]. This is analogous to a king who had slaves and maidservants, and he would marry maidservants from another estate to his slaves, and [marry] slaves from another estate to his maidservants. The king stood and considered.
He said: The slaves are mine, and the maidservants are mine; it would be preferable for me to marry my slaves to my maidservants, mine to mine. So, as it were, the Holy One blessed be He said: The land is Mine, as it is stated: “The earth is the Lord’s” (Psalms 24:1), “As the land is Mine” (Leviticus 25:23), and Israel is Mine, as it is stated: “For the children of Israel are servants to Me” (Leviticus 25:55).
It is preferable that I bequeath My land to My servants, Mine to Mine. That is why it is stated: “This will be the land that will fall to you as an inheritance.”
