וַיֹּ֕אמֶר הִנֵּה־נָ֖א זָקַ֑נְתִּי לֹ֥א יָדַ֖עְתִּי י֥וֹם מוֹתִֽי׃
At sinabi niya: “Narito, matanda na ako; hindi ko alam ang araw ng aking kamatayan.

Some difficulties in the text: 1) What kind of weak eyesight prevents a father from recognizing his son? Why would not Isaac's other senses such as hearing, touching etc compensate for his failing eyesight, and enable Isaac to recognize his sons? Why did Isaac issue instructions regarding the hunting of venison prior to his issuing the blessing? 2) Why did Rebecca change what Isaac had said? He had said, "I want to bless you before I die," whereas Rebecca related to Jacob that Isaac had said, "I will bless you before the Lord?" (compare Genesis 27,2 and 27,6). 3) Did it not occur to Jacob that his voice would give him away? 4) What is the relevance of "the odor of my son is like the odor of the field that the Lord has blessed?" 5) When Isaac discovered his error, he refers only to Jacob's deceit, not a word about his own error. Why? Why did Esau employ three arguments to secure a blessing, and why did he say that the days of mourning for his father would come "quickly?" Why not just "they will come?" Rebecca's fear she might be bereft of both sons in a single day seems to be somewhat ill founded. If Esau were to kill Jacob, who would kill Esau? 6) Why did Rebecca not reveal her true motives for sending Jacob away even at this late stage?
