Psalms 31:5 - Joseph Benson’s Commentary on the Old and New Testaments

Into thy hand That is, to thy care and custody; I commit my spirit My soul or life, either to preserve it from the malice of mine enemies, or, if they are permitted to kill my body, to receive it. For my case is almost desperate, and I am ready to give up the ghost. But our Lord used those words, when expiring on the cross, in a more proper and literal sense than they can be applied to David. He used them, probably, to convince the Jews that, though suffering, he was the Messiah, and that son of David who should sit on his throne for ever. For thou hast redeemed me Thou hast delivered me formerly in great dangers, and therefore I willingly and cheerfully commit myself to thee for the future: O Lord God of truth Who hast showed thyself to be such to me in making good thy promises.
