אל תירא אברם, do not worry that the four kings will avenge themselves on you.

שכרך, not only that, but your reward over and beyond that is so great that your merits have not decreased on account of your success in that battle. You deserve much more reward for having gone to the assistance of your brother, displaying a supreme degree of love for him and for those belonging to him. You have liberated the victims of kidnappers.

הרבה מאד, both in this world

and in the world to come. We have been taught, and recite daily in our prayers, that there are things for which one receives some dividends in this world, whereas the principal comes due in the hereafter. One of the good deeds which qualify for such reward is known as גמילות חסדים, the performing of deeds of loving kindness involving not only one’s checkbook but one’s very body (Peah, 1,1).

?מה תתן לי, a reference to the reward in this life.

ערירי, “I have no son who can take my place.” Compare Jeremiah 22,30 כתבו את האיש הזה ערירי כי לא יצלח מזרעו איש יושב על כסא דוד, “record this man as without succession; one who shall never be found successful, for none of his offspring will be accepted to sit on the throne of David.” (the subject of this curse is כניהו son and heir of Yehoyakim)

ובן משק ביתי הוא דמשק אליעזר, he is only a slave, known only in his home town. There can be no question but that similar actions performed by a slave who is in constant fear of his master’s disapproval, even if in fact the same as those performed by the master’s son, are different in quality, and in effect from one another. The same chores performed by the son are motivated by love instead of by fear.

בן ביתי יורש אותי, even though, in the end, You will give me biological offspring, as You have said in 12,7 לזרעך אתן את הארץ הזאת, “I will give this land to your descendants,” such children will only be minors at the time, so that my servant Eliezer will have to raise them and guide them, in effect being my heir.

לא יירשך זה כי אם אשר יצא ממעיך, for the son would succeed taking over Avram’s leadership role amongst large number of followers while his father was still alive. This is the true meaning of Genesis 25, 5-6 ויתן אברהם את כל אשר לו ליצחק בנו.... בעודנו חי,” Avraham handed over all that was his to his son Yitzchok while he was still alive.” This is followed by the statement that Avraham sent away the sons of the concubines from the presence of his son Yitzchok.

He believed. He had utter confidence that God would fulfill His promise, even if it required a miracle.

And this He accounted. God reckoned Avraham’s trust as an act of righteousness, which proves that his subsequent inquiry, “How will I know, etc.?” could not have been an expression of doubt.

אשר הוצאתיך מאור כשדים לתת לך את הארץ הזאת, for you, personally, will acquire this land by an act of taking symbolic possession of it.

לרשתה, so that the children (descendants) would inherit it from you under the heading of an inheritance, i.e. without any interruption in this land being owned by Israelites.

במה אדע, for possibly my descendants will sin and forfeit their claim to this land.

קחה לי עגלה, take a heifer for Me, in order to enter into a covenant concerning this assurance. Converting G’d’s promise into what is known as a “covenant,” is equivalent to G’d reinforcing His promise by an oath, something which is unconditional and irrevocable. (Rosh Hashanah 18) Moses himself confirmed this interpretation when he said (Deut 9,5) “not due to your righteousness or the uprightness of your heart, but due to the wickedness of these nations does G’d dispossess them on your account; and in order to keep His promise which He had sworn to your forefathers Avraham, Yitzchok and Yaakov

Know for sure. God’s main point here was that the inheritance of the Land had to wait until the sin of the Emorites was complete (v. 16). Along the way, however, He revealed the suffering that would befall some of Avraham’s offspring when they failed to live up to their obligations.

וגם את הגוי אשר יעבדו דן אנכי, just as I judge your descendants, for the wickedness with enslavement and cruel suppression, so I will judge the nation that enslaves them."
