Genesis 22:6

22:6 Abraham took the wood for the burnt offering and put it on his son Isaac. Then he took the fire and the knife in his hand, ¹  and the two of them walked on together.

Genesis 27:36

27:36 Esau exclaimed, “‘Jacob’ is the right name for him! ²  He has tripped me up ³  two times! He took away my birthright, and now, look, he has taken away my blessing!” Then he asked, “Have you not kept back a blessing for me?”

[22:6]  ¹ sn He took the fire and the knife in his hand. These details anticipate the sacrifice that lies ahead.

[27:36]  ² tn Heb “Is he not rightly named Jacob?” The rhetorical question, since it expects a positive reply, has been translated as a declarative statement.

[27:36]  ³ sn He has tripped me up. When originally given, the name Jacob was a play on the word “heel” (see Gen 25:26). The name (since it is a verb) probably means something like “may he protect,” that is, as a rearguard, dogging the heels. This name was probably chosen because of the immediate association with the incident of grabbing the heel. Esau gives the name “Jacob” a negative connotation here, the meaning “to trip up; to supplant.”
