Targum Pseudo-Jonathan:
15. And I will put enmity
between you and the woman, between the offspring of your children and the
offspring of her children. And when the children of the woman keep the
commandments of the Law, they will take aim and strike you on your head. But when
they forsake the commandments of the Law you will take aim and wound them on
their heels. For them, however, there will be a remedy; but for you there will
be no remedy; and they are to make peace in the end, in the days of the King
Messiah.”
Targum Neofiti:
15. And I will put enmity
between you and the woman and between your sons and her sons. And it will come
about that when her sons observe the Law and do the commandments they will aim
at you and smite you on your head and kill you. But when they forsake the
commandments of the Law you will aim and bite him on his heel and make him ill.
For her sons, however, there will be a remedy, but for you, O serpent, there
will not be a remedy, since they are to make appeasement in the end, in the day
of King Messiah.”
Targum Onqelos:
15. And I will place enmity
between you and (between) the woman, and between your children and (between)
her children, it will remember what you did to it in ancient time and you will
sustain (your hatred) for it to the end {of time}.”
