What is the meaning of "va'Asim Nafshi b'Chapi"?
1.
Targum Yonasan: I handed over (risked) my soul, like on back 1 to be killed. Radak - perhaps you would kill me, like you eradicated the Ovos and Yid'onim. Alternatively, engaging in raising the dead is dangerous.

Lev Yitzchak (Shoftim 12:3): Some texts of Targum Yonasan say "k'Al Gav Yadi", like the Targum in Tehilim 119:109 and Iyov 13:14. I.e. my life was prone to be lost, like something on back of the hand is prone to be dropped.
