Some References to the Trinity?

I am totally speculating here. I would definitely NOT use these as in any apologetic argument. I am simply putting these here as a reminder for me to maybe later put them in my apologetic/catechetical/spiritual/application Bible.

EXAMPLE 1
As the spiritual leader in my home (not a very good one). I sometimes bless my children before bed as my father/mother blessed me;

"God bless you with a happy life, a happy death, and peace in mind."

Someone suggested that I use the prayer from Numbers 6:24-26 (RSV;SCE)

 The LORD bless you and keep you: 
 The LORD make his face to shine upon you, and be gracious to you: 
 The LORD lift up his countenance upon you, and give you peace. 

I noticed that it mentioned the LORD (Yahweh) three times. I wonder if this is a little reference to the Trinity?

I remembered what the Catechism of the Catholic Church said:
CCC 1078 Blessing is a divine and life-giving action, the source of which is the Father; his blessing is both word [Jesus is the WORD] and gift [The Holy Spirit is the Gift of the Father].

Then I noticed how in verse 25 it mentions the face of the LORD and I thought of course of Jesus's face. (It does mention his face again in 26 [countenance], so that kind of throws a wrench in the whole deal). But the triple reference made me think of the Trinity.

 The LORD [Father] bless you and keep you: 
 The LORD [Son] make his face to shine upon you, and be gracious to you: 
 The LORD [Holy Spirit] lift up his countenance upon you, and give you peace. 

EXAMPLE 2
While reading Genesis 1:27 I thought of something similar.

So God created man in his own image, 
in the image of God he created him; 
male and female he created them.

Why the triple reference to one event. Then I remembered the Catechism:
CCC 292 The Old Testament suggests and the New Covenant reveals the creative action of the Son and the Spirit,  inseparably one with that of the Father. This creative cooperation is clearly affirmed in the Church’s rule of faith: “There exists but one God … he is the Father, God, the Creator, the author, the giver of order. He made all things by himself, that is, by his Word and by his Wisdom,” “by the Son and the Spirit” who, so to speak, are “his hands.” Creation is the common work of the Holy Trinity.

So again, speculating...

So God [Father] created man in his own image, 
in the image of God he [Son] created him; 
male and female he[Holy Spirit] created them.

EXAMPLE 3

Mark 1:1-3
The beginning of the gospel of Jesus Christ, the Son of God.
As it is written in Isaiah the prophet,
“Behold, I send my messenger before your face, 
who shall prepare your way; (Micah 3:1)
the voice of one crying in the wilderness: (Isaiah 40:3)
Prepare the way of the Lord, 
make his paths straight—”

Again, speculating... but it does mention a road/path three times.

“Behold, I send my messenger [John the Baptist] before your face, 
who shall prepare your [Father] way; (Micah 3:1)
the voice of one crying in the wilderness: (Isaiah 40:3)
Prepare the way of the Lord [Son] , 
make his [Holy Spirit] paths straight—”

Done. Unless you have seen some others, I would be curious.
