From Strong's Exhaustive Concordance

1. Holy, holy, holy! Lord God Almighty!

   See definition oh Holy above – Shaddai God almighty
   Early in the morning our song shall rise to Thee.

   Begin the day by singing of God's holiness and grace
   Holy, holy, holy, merciful and mighty,

   See definition oh Holy above – God is the perfect balance of power and mercy
   God in three Persons, blessed Trinity!

The Trinity is The Lord our God is one, in three persons of Father, Son and Holy Spirit

2. Holy, holy, holy! All the saints adore Thee,

   See definition oh Holy above – Saints who are, were and shall be
   Casting down their golden crowns around the glassy sea;

   We will receive crowns which we will lay at the feet of Jesus who enabled us
   Cherubim and seraphim falling down before Thee,

   Angelic beings protecting Eden and God's Throne – Angelic beings with six wings and human voices who protect God's Throne
   Which wert, and art, and evermore shalt be.

Time which was created by the Triune God is also a Trinity. God is beyond time

3. Holy, holy, holy! Though the darkness hide Thee,

   See definition oh Holy above – God has placed a veil (like in the Temple) to protect us from seeing Him directly
   Tho' the eye of sinful man Thy glory may not see;

   If we see God directly we will die
   Only Thou art holy; there is none beside Thee,

   God alone is holy and is above all of Creation
   Perfect in power, in love and purity.

God is even perfection in trinity

4. Holy, holy, holy! Lord God Almighty!

   See definition oh Holy above – Shaddai God almighty
   Early in the morning our song shall rise to Thee.

   Begin the day by singing of God's holiness and grace
   All Thy works shall praise Thy name, in earth and sky and sea.

   Again we see the trinity this time of Creation – All Creation joins in worship
   Holy, holy, holy, Merciful and mighty,

   See definition oh Holy above – God is the perfect balance of power and mercy
   God in three Persons, blessed Trinity.

   The Trinity is The Lord our God is one, in three persons of Father, Son and Holy Spirit
