"Ariri" [stripped, childless, bare of children] in the two traditions here, they wrote this man as "Ariri" in the Jehoiachin tradition, because the Jehoiachin exile showed him that Abraham left Ur of the Chaldeans, and they were exiled to the Chaldeans who were in Babylon.

"And he brought him outside" in gematria equals איצטגנינותך [astrology or horoscope]. This means that your offspring will be like the number of letters in איצטגנינותך [astrology or horoscope.] - which is 25. In other words, your offspring will be as numerous as 25. This is because at the time of the covenant between the pieces, Abraham was 75 years old.

The word "yihyeh" (meaning "it shall be") has the gematria of 30. This teaches us that in every generation there are at least 30 righteous individuals. Similarly, it is said "yihyeh" (it shall be) to teach that in your offspring there will be righteous individuals, as it is said: "And He said to him, 'So shall your offspring be.'" (Genesis 15:5)

"ויחשבה" is mentioned three times in the Torah. Here, it refers to Tamar, who was suspected of prostitution. It also refers to Hannah, who was suspected of being drunk. This is what Rabbi Isaac Luria meant when he said that my portion is with those who are suspected but are not guilty, as Tamar, because she was suspected, was ultimately vindicated and gave birth to Perez and Zerah, from whom kings and prophets descended. Hannah, because she was suspected, was ultimately vindicated and gave birth to Samuel. Therefore, even though they were suspected of being a prostitute or drunk, they are considered righteous. (Commentary by Rabbi Asher ben Yechiel)

"What will I know?" In the context of the prohibition of the Torah. Blessed be His name, the conversation of Isaac arrived at the calculation of 400, and therefore a decree of 400 was decreed upon his children. "What will I know" in the calculation, that two years were added at the end of the years when no man passed in Judah, and seventy were in exile.

ויהי השמש "And it was the sun" in the tradition. Here and elsewhere "and it was the sun" comes [in the context of destruction]. Corresponding to the two Temples, as it is written (Jeremiah 6:26), "And I will set your suns [i.e. Temple courtyards] and your gates for destruction."

For the phrase 'a stranger' כי גר final letters [י and ר] has the numerical value of 210, which corresponds to the actual years of slavery in Egypt.

"And generation" two" in the tradition here and another generation comes. The meaning is that one generation leaves when your children leave the land and another generation comes to inherit the land. And the fourth generation will return here. (Note: this is a reference to the prophecy in Genesis 15:16 regarding the Israelites' time in Egypt and eventual return to the Promised Land.)
