Charles H. Spurgeon on Psalms 31:5

Into thine hand I commit my spirit. These words, as they stand in the Vulgate, were in the highest credit among our ancestors; by whom they were used on all dangers, difficulties, and in the article of death. In manus tuas, Domine, commendo spiritum meum, was used by the sick when about to expire, if they were sensible; and if not, the priest said it in their behalf. In forms of prayer for sick and dying persons, these words were frequently inserted in Latin, though all the rest of the prayer was English; for it was supposed there was something sovereign in the language itself. But let not the abuse of such words hinder their usefulness. For an ejaculation nothing can be better; and when the pious or the tempted with confidence use them, nothing can exceed their effect. Adam Clarke.
