Psalms 71:14-18

MLV(i) 14 But I will hope continually and will praise you yet more and more. 15 My mouth will tell of your righteousness, of your salvation all the day, because I do not know the numbers.
16 I will come with the mighty acts of the lord Jehovah. I will make mention of your righteousness, yours only!
17 O God, you have taught me from my youth and I have declared your wondrous works until now.
18 Yes, even when I am old and gray headed, O God, forsake me not, until I have declared your strength to a generation, your might to everyone who is to come.
