M. Tullius Cicero Cum Senatui Gratias Egit 30

[30]
  And by what services can I requite the kindness of Titus Annius to me? all whose actions, the whole of whose conduct and thoughts, the whole of whose tribuneship, in short, was nothing else except a consistent, continual, gallant, unwearied advocacy of my safety.
  Why need I speak of Publius Sextius? who showed his good-will and faithful attachment to me, not only by his grief of mind, but even by the wounds which he received on his person.
  But to you, O conscript fathers, and to each individual of you, I have both declared, and I will continue to declare my gratitude. I declared it at the beginning to your whole body, as well as I could; to declare it with sufficient eloquence is what I am totally unable to do. And although I have received special favours from many persons, about which it is impossible for me to keep silence, still it is impossible at the present time, and with the apprehensions which I feel, to endeavour to enumerate the kindnesses which I have received from individuals. For it is difficult to avoid passing over some, and yet it would be impious to forget any one. I, O conscript fathers, ought to reverence every one of you as I do the immortal gods. But as, even in the case of the immortal gods themselves, we are wont not always to pay worship and to offer prayers to the same deities, but sometimes we pray to one and sometimes to another; so in the case of the men who have behaved to me with such godlike service, my whole life shall be devoted to celebrating their kindness towards me, and showing my reverent sense of it.
