For you, O Lord, are my hope,
my trust, O LORD, from my youth.
Upon you I have leaned from before my birth;
you are he who took me from my mother’s womb.
My praise is continually of you.

I have been as a portent to many,
but you are my strong refuge.
My mouth is filled with your praise,
and with your glory all the day.
Do not cast me off in the time of old age;
forsake me not when my strength is spent.

O God, be not far from me;
O my God, make haste to help me!

But I will hope continually
and will praise you yet more and more.
My mouth will tell of your righteous acts,
of your deeds of salvation all the day,
for their number is past my knowledge.
With the mighty deeds of the Lord GOD I will come;
I will remind them of your righteousness, yours alone.

O God, from my youth you have taught me,
and I still proclaim your wondrous deeds.
So even to old age and gray hairs,
O God, do not forsake me,
until I proclaim your might to another generation,
your power to all those to come.
