(Lev. 19:23:) “When you come into the land.” Solomon said (in Prov. 31:16), “She sets her mind on a field and acquires it.” Come and see. Whatever Abraham thought about in his heart the Holy One, blessed be He, gave him. He thought [about] the land of [Israel], and He gave it to him, as stated (in Gen. 15:7), “I am the Lord who brought you out from Ur of the Chaldees [to give you this land as a possession].” Abraham said to the Holy One, blessed be He, “Master of the world, You have given me permission to speak in front of You, as stated (in vs. 8), “And he said, ‘Lord God, how shall I know that I shall possess it?” He replied and said to him (in vs. 13), “Know full well [that your seed shall be aliens in a land not theirs where they shall serve them and be oppressed by them].” Woe to that person who brings something out of his mouth without knowing how he brought it out. Because Abraham said (in vs. 8), “how shall I know,” He answered him, “Know fully well… they shall serve them and be oppressed by them for four hundred years.” One who speaks [like this] in front of any man is liable for his life; all the more so is he liable for his life if he speaks in front of the Holy One, blessed be He; he and his children and his children’s children until the end of all the generations [and] until the revival of the dead. It is not sufficient for these until the time of judgement, the time that a person’s soul withdraws from him. So did Solomon yell out (in Eccl. 6:7), “Is all human toil for one's mouth?” All the commandments and righteous deeds that one does; it is enough for the time that one's soul goes out of him. It is therefore stated (in Eccl. 6:7), “Is all human toil for one's mouth?” When Abraham heard from the Holy One, blessed be He, (in Gen. 15:13), “Know full well,” he thought about it in his heart and said, “Is it possible that every people which enslaves my children goes away in peace and is not condemned?” The Holy One, blessed be He, said to him (in Gen. 15:14), “But I am also judging the nation which they shall serve….” It is therefore stated (in Prov. 31:16), “She sets her mind on a field and acquires it.”
