My soul is continually in my hand: yet do I not forget thy law. My soul is continually in my hand - נפשי naphshi, my life; that is, it is in constant danger, every hour I am on the confines of death.
The expression signifies to be in continual danger. So Xenarchus in Athenaeus, lib. xiii., c. 4: Εν τῃ χειρι την ψυχην εχοντα, "having the life in the hand;" which signifies continual danger and jeopardy. There is some thing like this in the speech of Achilles to Ulysses, Hom. Il. ix., ver. 322: -
Αιει εμην ψυχην παραβαλλομενος πολεμιζειν·
"Always presenting my life to the dangers of the fight."
My soul is in thy hand, is the reading of the Syriac, Septuagint, Ethiopic, and Arabic; but this is a conjectural and useless emendation.
