창세기 12:1 할라카: Peninei Halakhah, Family & Mishneh Torah, Prayer and the Priestly Blessing

The first personal mitzvah given to the first Jewish person was the mitzvah of circumcision. However, according to all [other opinions] it was the mitzvah of going up to the land [of Israel], as it is said "Ad-nai said to Abram, 'Go forth from your native land and from your father’s house to the land that I will show you.'"However, the mitzvah of settling the land is a collective mitzvah, that encompasses all those living in the Jewish people in general, and the life of every Jewish individual in particular, but as a personal mitzvah the circumcision is the first mitzvah. There is a connection between the mitzvah of settling in the land and circumcision, since through those two mitzvot holiness reveals itself both in body and in physicality. Through settling in the land it becomes clear that there is value in every act of work that is connected to the building of the land, and through the brit milah it becomes clear that there is holy value to the body, therefore the orlah needs to be separated from it.

And so we find that the sages said about Avraham our Father, who worried about getting out of Haran and abandon his father Terach on his old age, and God said to him "Go forth from your native land and from your father’s house to the land that I will show you" (Gen. 12:1), and [God] exempted him with this from the mitzvot related to honoring parents (Bereshit Rabbah 39:8). And so our sages said that Yaakov our Father was punished through his son Yosef abandoning him for 22 years, because he himself abandoned his parents and went to Haran for 22 years. And even though Yaakov was compelled to flee his brother, who wanted to kill him, and did this because his parents commanded him to; due to the fact that nevertheless he did not honor his parents during that many years, and also due to the fact that he did not return quickly when he was able to, he was punished. Despite all this, for the needs of studying Torah a person can leave their parents: we find that Yaakov our Father went to the house of study of Shem and Ever, and learned there for 14 years, and was not punished for that (see Megilah 17a).

The custom prevailing through Israel is [that the reading of the Pentateuch is completed in one year]^*The passage in brackets is omitted in the manuscript, apparently erased.. It is begun on the Sabbath after the feast of Tabernacles, when the portion commencing Bereshith "In the Beginning" (Genesis 1:1) is read. On the second Sabbath, that beginning, "These are the generations of Noah" (Genesis 6:9) is read; on the third, that beginning, "And the Lord said to Abraham" (ibid. 12:1), and so on in regular order till the last portion is read on the feast of Tabernacles. Some complete the reading of the Pentateuch in three years, but this is not a prevalent custom.
