Genesis 25:26 New English Translation

²⁶When his brother came out with^[a] his hand clutching Esau’s heel, they named him Jacob.^[b] Isaac was sixty years old^[c] when they were born.

Genesis 25:26 tn The disjunctive clause describes an important circumstance accompanying the birth. Whereas Esau was passive at birth, Jacob was active.
Genesis 25:26 tn Heb “And he called his name Jacob.” Some ancient witnesses read “they called his name Jacob” (see v. 25). In either case the subject is indefinite.sn The name Jacob is a play on the Hebrew word for “heel” (עָקֵב, ʿaqev). 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.
Genesis 25:26 tn Heb “the son of sixty years.”
