tn The disjunctive clause describes an important circumstance accompanying the birth. Whereas Esau was passive at birth, Jacob was active.
sn The name Jacob is a play on the Hebrew word for “heel” (עָקֵב, ’aqev). The name (since it is a verb) probably means something like “may he protect,” that is, as a rearguard, dogging the heels. It did not have a negative connotation until Esau redefined it. This name was probably chosen because of the immediate association with the incident of grabbing the heel. After receiving such an oracle, the parents would have preserved in memory almost every detail of the unusual births.
tn Heb “the son of sixty years.”
