Charles H. Spurgeon on Psalms 70:5

I am poor and needy. By this I hold to be meant the chastisements, and fiery trials that come from God the Father; the temptations and bitter assaults of that foul and fell fiend, Satan; the persecutions and vexations inflicted by the hands of unreasonable and wicked men; and (but in this following Christ must be exempted) the inward corruptions, disordered motions, unsettled affections, and the original pollutions brought from the mother's womb; with the soul and body's inaptness and unableness with cheerfulness and constancy to run the direct and just paths of God's commandments. Many of these made the Head, all of these (and more, too) the members, poor and needy. John Barlow. 1618.
