Charles Ellicott Commentary Psalms 31:5

"Into thy hand I commend my spirit: Thou hast redeemed me, O Jehovah, thou God of truth." — Psalms 31:5 (ASV)

I commit. —Most memorable, even among expressions of the Psalms, as the dying words of our Lord Himself (Luke 23:46), and a long line of Christian worthies. Polycarp, Bernard, Huss, Henry V., Jerome of Prague, Luther, Melancthon, are some of the many who have passed away comforted and upheld by the psalmist’s expression of trust. But death was not in his thought; it was in life, amid its troubles and dangers, that he trusted (Hebrew, deposited as a trust) his spirit (rûach, compare to Isaiah 38:16) to God. But the gift brought to the altar by the seer of old has been consecrated anew and yet anew.

Lord God of truth. —Compare to 2 Chronicles 15:3, where, as here, there is a contrast between Jehovah and idols; but also, as in Deuteronomy 32:4, the faithful God.
