1 Samuel 26:11-13

11 But Ammon said unto him: I do not boast in my own strength, nor in my own wisdom; but behold, my joy is full, yea, my heart is brim with joy, and I will rejoice in my God.

12 Yea, I know that I am nothing; as to my strength I am weak; therefore I will not boast of myself, but I will boast of my God, for in his strength I can do all things; yea, behold, many mighty miracles we have wrought in this land, for which we will praise his name forever.

13 Behold, how many thousands of our brethren has he loosed from the pains of hell; and they are brought to sing redeeming love, and this because of the power of his word which is in us, therefore have we not great reason to rejoice?
