1) Rashi HaKadosh explains that the verse saying ‘licha/for yourself’ implies ‘for your benefit’.
2) Now, what does that go to teach us? I believe it is telling us that when you do Hashem’s Word (as going, in this case would be), it always ends up good for you.
3) The Rebbe Reb Zusia of Anipole zt”l explains that the word ‘eretz/earth’ can imply earthliness. And so he says that this verse is teaching us that we will not be able to come to the place that Hashem shows us until we get rid of our earthliness and concentrate more on spirituality.
4) His brother, the Noam Elimelech (The Rebbe Reb Elimelech of Lizhensk zt”l) explains that ‘Lech licha/go for yourself’ can also mean ‘go to yourself’ – implying to go into yourself. This, he explains, teaches us that a person must go into themselves, so to speak, and try to get rid of all the bad that there is.
5) The Divrei Yisroel (the first Modzitzer Rebbe - Rebbe Yisroel Taub zt”l) quotes the Midrash, which explains that the word ‘eretz/earth’ can imply ‘ratzon/will’: So, he says, this verse is teaching us that we must go from our will (‘from your land’) and come to Hashem’s Will (‘to the land that I will show you’). Meaning that, (similar to what we were discussing before), we must try to stop caring as much about our desires, and think more about Hashem’s Will.
7) The Rebbe Reb Zusia zt”l says another great lesson we can learn from this verse: The Torah teaches us by saying ‘Go to yourself’, he explains, that a person must go in life by using themselves. Meaning that we must use the special talents that Hashem has given us individually, to fulfill our special mission in life.
1) Rashi HaKadosh quotes from the Sages in Midrash Bereisheis Rabbah and Nedarim 32a, who say that the “318 men” were actually Eliezer Damaseik alone, because the Gematria/numerical value of the Hebrew word ‘אליעזר ’ is 318. (However, there is another opinion that the 318 men were Avraham Avinu’s students.
2) Rebbe Avraham Schorr shlita explains the 318 men homiletically: Why, he asks, would Avraham Avinu bring specifically 318 men? Why 318? And he explains that 318 is one more than the Gematria/numerical value of the Hebrew word ‘יאוּשׁ’ which means ‘despair’, i.e. to give up. So he says that Avraham Avinu wanted to bring 318 men in order for it to be one more than ‘yeush/despair’ to teach us never to give up. It would be easy to give up in Avraham’s position – 300-some people on one of the strongest armies out there!! But he didn’t; he trusted in Hashem, and Hashem delivered the kings and their armies’ into his hands. We must try to never give up – ‘Hashem’s salvation comes in the blink of an eye’ and He can always help us. May He help us to never give up on anything good, Amein, vi’Amein.
Okay, back to the parsha: Avraham then, with his servants split up, smote the four kings, and took back Lot and all his possessions. In the middle of Chamishi/the fifth Aliyah, the Torah talks about how Hashem appeared to Avraham, and told him that He was his Shield and that his reward was very great. But Avraham really wanted a kid. And Hashem came to him and told him that he would have a kid. Hashem showed him the stars, and said that basically you will be able to count his offspring just as much as you can count the stars.
Rashi HaKadosh says that the reason why Hashem said ‘Nasati/I have given’ is because when He says something, it is like an accomplished fact. Meaning that it is like it has already happened because Hashem is always true to His Word. We need to learn from Him to be very truthful as well, and try to never, Chas V’Shalom, be false. Now, Sarah saw she didn’t have any kids, so she gave Hagar to Avraham as a wife, so that she (Sarah) would be built up through her, and Hagar had Yishmael. Avraham was 86 when he had Yishmael.
Have a wonderful, wonderful week everyone!
