Psalms 25:5

Lead me in thy truth, and teach me: for thou [art] the God of my salvation; on thee do I wait all the day.

Ver. 5. Lead me in thy truth, and teach me] i.e. Assidue doce et urge. David was a great proficient in God's school, and yet he would learn more; so sweet is divine knowledge. Four times together here prayeth David to be further instructed. See Moses in like manner holily encroaching upon God, Exodus 33:12,13; Exodus 33:16; Exodus 33:18, as if his motto had been that of Charles V, Ulterius, More yet.

For thou art the God of my salvation] Perfect, therefore, that which concerneth me. "Thy mercy, O Lord, endureth for ever; forsake not the works of thine own hands," Psalms 138:8. Thou hast written me down in thy book of preservation with thine own hand. Oh read thine own handwriting, and save me, said Queen Elizabeth in her troubles.
